People
believe all sorts of foolish things which have no basis in science. Repeating things over and over again does not make them true. The science has not filled in all the blanks, but this is the picture as it currently stands:
What we know, as Dienekes pointed out, is that the E-V13 in the Balkans experienced a large
expansion in the Bronze Age, and from a small group of founders, apparently, as it has very little diversity. For some reason, it was in a very lucky position. It might be that it was connected in some way with bronze weapons. It's also probable that the E-V13 in Italy is due to migration from the Balkans or Greece.
None of those things tell us
when it arrived in the Balkans, or from where, but the phylogeny certainly provides evidence that it came from the Near East. (I don't know where this Caucasus thing comes from...the yDna most associated with the Caucasus is "G" and "J", not "E".)
It's also
possible, as some early papers posited, that E-V13 arrived in southeastern Europe in the Mesolithic, but as time passes and all the ancient dna from that period turns out to be some form of I2, that's looking less and less likely. Still, we don't have any yDna from the Aegean yet, so there's still a chance that some moved into that area in the Mesolithic. After all, it's hardly an insurmountable distance.
What is also true is that whether it had reached the periphery of south-eastern Europe by the time of the Mesolithic, or accompanied the G farmers directly from the Near East, or both, the findings in Neolithic contexts in other early Cardial sites means that it was part of the early Neolithic expansion. It may have been and probably was in the southeast from that time, as the samples also show. What we are seeing in the Balkans today is that a lot of the E-V13 is from a lineage which, as I said, underwent a massive expansion during the Bronze Age. Whether the lineages in southern Germany, for example, are part of the same group or descendents of different sub-clades or both, we don't know yet know.
Oh, it's possible that the specific "E-V13" mutation took place in Europe, but I currently don't see evidence for that, given that there are non-negligible amounts in the Near East even after the massive expansions there of J1 and J2. Let's not forget that G2 has also been superseded in the Near East. It survives in the Caucasus in such high numbers mainly, in my opinion, because it is an area of refuge.
See the following for a map of the spread of the y lineages:

I would also caution against attempts to tie ydna to autosomal percentages too strictly. We all have mothers too. The English are close to 50% EEF, and yet they have negligible amounts of E and J and T. Plus, by the time that the R1b and R1a men got to Europe, we don't know how much "Mediterranean" ancestry they carried.
One final thing as to I2a. It's clear that it was a fisher/hunter gatherer lineage present in Europe before the arrival of farming. However, some clades apparently made the transition to farming very early, perhaps from a group around the Danube Gorges, and became part of the Neolithic farmer world, to show up in Sardinia and Iberia, for example. Others may have fled into more northern areas, only to be neolithicized by the Indo-Europeans perhaps and then return with the Slavs. Whether some subclades remained in the more southern reaches of the Balkans we don't know. None of this will become clearer until we have ancient dna from the relevant groups at a reasonable level of resolution.
For a general overview of all of this, I often recommend Jean Manco's Ancestral Journeys. As the new discoveries are coming fast and furiously, I am sure she is already preparing a new edition, but it's an excellent book and a good primer for this field of study, whether she turns out to be correct in every particular or not.
The fact that E-V13 was part of the early Neolithic is incontrovertible. As is the fact that the sample was found in the
Iberian Neolithic. (This means that E-V13 has been in Europe for at least 7,000 years, longer than the "R" lineages, at least so far as our current ancient samples would indicate.)
That doesn't tell us where it originated. The phylogeny would indicate that it is sourced in the Near East, although it's possible, as Maleth pointed out, that the mutation occurred in Europe. I still think that it is more likely it originated in the Middle East, given the levels in the Druze, a population that seems to have preserved the more ancient lineages of the Middle East, but it wouldn't at all surprise me to discover that Maleth is correct.
The editor of the "E" pages on Wiki is very knowledgeable, in my opinion, and so I think that the following page gives a very nice summary.(You can jump to the E-V13 section.)

See also the Marie Lacan et al paper which found the ancient E-V13 sample:

As to the route that E-V13 took to reach Iberia, the Avellenar site is an epi-Cardial one. This is a good map of the Cardial migrations as determined by archaeology:

Note that according to some researchers, at least, the start of the Cardial culture in Europe can be located on the Adriatic in the Balkans.
It's true that there were Cardial sites in North Africa and some have posited a movement from those sites into Iberia.

However, please note the location of the Avellenar site:

Given this location and the correspondences between Avellenar and Treilles, I think it highly likely that Avellenar was part of the Cardial expansion that moved along the northern Mediterranean.
If someone wishes to quibble with the Bronze Age date (based on pedigree type rates) for the expansion of E-V13 in the Balkans, that's fine. The alternative is to use the Zivitovsky rate which is
2 1/2 times slower, which would mean it had its massive expansion way back in the Neolithic.
There is no evidence whatsoever, to my knowledge, linking E-V13 to the Caucasus (that is G and J2 country) or the Turks, or some mythical group of Egyptians. Nor is there any indication so far that it came to Europe by way of Gibraltar. That is highly probable, of course, for at least some of E-M81, which has a very different history and distribution.
We try to deal with science and recorded history here, not myths or things used as calumnies of one sort or another.
It would help further discussion to read the relevant cited papers. and if there is disagreement, to cite contradictory papers.
