Since it took 3.5 billion years for life to progress pass 1 cell, and, that very few stars make it past 1/2 billion, let alone 1 billion (most of the ones that do go longer are red dwarf stars and they pump out a huge amount of radiation), other than various one celled life is about all there is a chance to be out there.
You got to have the right star, with a planet in the right place, with a moon to stabilize things, the right material make up, and, a safe part of the galaxy.
Life is more specialized that they lead you to believe.
I believe all the evidence we have points to life being extremely rare.
