@Ygorcs
it is moesan that mentioned in his post that steppe had already entered western europe....he said clearly western europe now in your reply you mention southeastern europe....I did not mention that region. So it is off the mark. No steppe in western europe till BBC.
Also I did not confuse the megalith stuff with Hamangia. I was only talking of different stages of european farms influence on the steppe: the cultural one: religion , burial custom ( earlier) and the genetic input ( later ). The farmer component that we find in central and south central asia ( andronovo, sintashta, srubnaya, ) is a consequence of a back migration of corded ware from eastern central europe after another mixing with the farmers independently of the one that happened in south eastern europe before.
Also your example of diffusion of religion is a good one if you talk about historical times and relationship between strongly structured culture Rome, Egypt, China India. Of course in "historical" time religion and language often do not match ( with the notable exception of islam ) Here we are talking about prehistory and the formative stage of the cultural ethnogenesis of the steppe. We are not talking about the relationship between Israel and Rome. Different age, different dynamics. So the religious influence from the west at that time with the steppe in its formative age was more likely to have triggered a language shift.
For the WHG Anatolia stuff....your reaction is psycho-like. Again ......did I mention the IE problem? Did I say that WHG in Anatolia created a PIE? Did I say that?

When it came to actually looking at the ancestral breakdown of Anatolians, Lazaridis et al. (2016) came up with a very solid model where Anatolians were a mix of lineages related to Ganj Dareh, Levant Neolithic, and WHG, with mixture proportions of 0.387, 0.339, and 0.274, respectively.
