Life on other planets?

Of course there is. The universe is huge. One thing I don't understand is why they're searching life on earth-like planets...I'm sure some weird creature could have evoluted in a way it can survive on a planet where we wouldn't survive a second.
 
There are high possibilities that there might be Earth-like life in the astral zone of Epsilon Eridani. This system is very familiar to our Solar system.
 
Think the Chinese informed on Tuesday,15th Jan 2019, that they had succesfully planted, and grew some plants on the moon ,but its reported that they had then died by Thursday,17th Jan 2019, due to the extreme cold conditions.

If life is found it is going to be 'very very' different, to that on Earth. Look at the vast extreme differences of species of life found on Earth today, and those that we know previously existed. Earth has a very 'unique' history of differing enviroments throughout its existance. We are still finding new forms or species of life, on Earth yearly I believe, and there are many more to find no doubt.

We have no idea what intelligence and life exists yet in space, but the idiots at 'Nasa' should never of sent that probe into deep space in my opinion, telling any 'life',' we are 'here' and 'Hello'. Earthlings may soon come to regret those actions by a 'very tiny few' that possibly could put billions at future risk.

I also believe the only impression, any other alien life that comes across us, can possible have is negative, as they cannot fail to see, and understand the recent mess we create on our Earth, and the fact that we keep killing each other, and almost every, other species, that exists, we come across or we find here. Any sensible 'alien life' with even the very least grain of intelligence would rightly ignore us, probably as they have done up too now, or destroy us for there own future safety.

There is today a recent set of opinions regarding the planet 'Mars', some people are pushing/supporting a view that evidence of two possible nuclear explosions exist there. They assume that these were 'manufactured explosions', and were responsible for totally wiping out all, or any life that was believed to of been in existance there, at that time.

Space is a very violent place, and any life will no doubt have to be born or develope from this violence. Therefore any exterrestrial intelligent life must be aware, or have its knowledge of this, and looking for other life in space,, the way we have, might not be the best way forward. We could or might end up on some aliens plate, or stuck in some type of test tube...lol

There is likely life somewhere in the universe. Does that life resemble humanoids? Little grey/green men with big eyes? Hell no! They likely resemble jellyfish.
 
Here is a list of discovered exoplanets around other nearby stars, that seem to have all the conditions to host life as we know it on Earth. (Earth is for comparison)
So when we get to them, genetics will work even more... :laughing: [TABLE="class: wikitable sortable jquery-tablesorter"]

I think all this is possible. Sometimes it seems to me that my whole life is a complete dream, and when I wake up I will be committed by another person.
 
I am quite sure there is somebody on other planets and in other galaxies, with a higher IQ level and with more performant things in their arsenal.
 
Complete Guide to Power Off Your iPhone or iPhone X

After a certain period of inactivity, the iPhone is automatically configured to go to sleep mode to consume battery life of your iPhone or iPhone X, by default settings. However, it is good for your device, but many times users may be stuck in the situations where they need to power off their iPhone completely. Well. Powering off the iPhone or iPhone X is useful in those cases when the battery is getting low, or your iPhone is fully discharged. The next reason for powering off the phone is when your iPhone performs or behaves weirdly, then restarting your iPhone is the only reliable, and the best solution users have. Powering off an iPhone is one of the best ways for turning off all notifications, alerts, phone calls, messages and many other things users want to stop. We suggest you to use Do Not Disturb mode which is quite good and has many other benefits for saving your phone and extra efforts.
 
How To Use Hashtags On Popular Social Media Networks

Putting a hashtag is a fantastic way to differentiate between different sections of the stuff that you post on any of your social media accounts. The hashtag(#) can be put in any word or sentence.
 
Given hundreds of billions of galaxies, each with hundreds of billions of stars and planets, it does seem quite implausible that out of all those many quadrillions of planets, Earth is the only planet with life. There are only about 80 stable (non-radioactive) elements in the universe. They are all found on earth and probably on countless other rocky planets. About 25 of those elements are essential to human life, and it is likely to be similar for complex life elsewhere in the universe.

So, the ingredients for life are widespread in the universe. The problem is we don't know exactly what conditions are required for life to start on a planet, or how rare or common those conditions are on other planets. For example, it has been argued that protection from cosmic radiation is necessary for life to begin, and that Earth has that protection because its iron core produces a magnetic field that deflects the sun's cosmic radiation. Some argue that a large moon such as our moon is necessary to stabilize the planet's rotation, and the surface temperature range. Liquid surface water is usually said to be another necessary pre-condition for life. Even if all that is true, and even if there are other pre-conditions for life we don't even know about, such that only one in a billion planets has the necessary conditions for life, that would mean that there are hundreds of other planets with life in the Milky Way alone, and trillions more in other galaxies.

Given simple life on a planet, the other interesting question is how often, and on what time scale, does life evolve from simple to complex to intelligent life with space technology. Life on Earth has existed for about four billion years, but life with space technology for only a little over one hundred years. I'm taking radio transmissions into space as the beginning of the age of space technology, and those transmissions began around a hundred years ago. If the ratio of four billion to one hundred is taken as a rough indication of the probability of any life relative to the probability of life with space technology, then only one planet in forty million with life might be expected to have life with space technology. So, even if there are a million other planets with some form of life in the Milky Way, ours might be the only planet in our galaxy that is capable of sending and receiving messages from other planets at this point in time. Our technology is much too recent for our messages to have reached other galaxies, and we could only detect messages from other galaxies, even nearby galaxies, if those messages were sent millions of years ago, perhaps by a civilization that no longer exists. We shouldn't be too surprised that we have no evidence yet of intelligent life elsewhere.
 
There is a billions planets even more, so I'm sure that there even 0.0000000000000000000000000000000001% but exist
 
Life already existed on mars

Until fossil evidence is found there, that is conjecture. It will remain an open question until Mars is studied more thoroughly.
