if life was as possible to have it in other places, there is also a chance other places have advanced faster or close by and we would be bale to detect some form of technology/waves, so chances are if there is other life it's a long long way from here.
as for not knowing the chance of life being made they smashed the basic building blocks for life up simulating a meteor strike, they found these basic building blocks will combine but the chances of them forming in a way that would support a life form is tiny, if it really was that possible for it to happen on 2 planets so close together the lab experiment would of shown results as the chances of it happening would be quite high.
I still stand by if we are going to find life we need to concentrate on getting out of our solar system.
@TheXand, you destroyed your planet because of the tech you are using want to basically reset, your not going to use the same tech again, the theory is they seeded the life on the planet got rid of their tech then either died out or slowly lost the ability to make their own tech (due to not teaching it) so eventually you ended up with a low advancement species ready to rebuild from scratch, but the fact remains it is most likely a load bollocks and just a crackpot theory.
