Simple math will tell you that if you have an infinite number of planets circling an infinite numbers of stars then since spontaneous life is possible is not improbable it is undeniable. There is science that creates an all knowing and all powerful being out of nothing so there is mathematical probability for it to occur. Evolution is not the best possibility it is the only reasonable explanation.
The one thing we can tell about god is that humans have a universal need to create one in order to make them feel they don't live in an arbitrary and uncaring universe. We tend to lock on the one we born into or if that doesn't fit find the one that appeals to us. Sorry but just because my grandparents believed in the teaching of bronze aged goat herders looking to explain why they kept being conquered is no reason for to unquestionably accept those beliefs when both science and the historical record proves them false.
It does not matter how unlikely life is if it is possible it will appear over and over again. It does not mater how unlikely it is to have happened here because the places where life not only formed but managed to take the giant leap to sentience are the only places discussing how improbable it is. No one on Mercury wonders why life didn't form there.
Abiogenesis is an interesting theory and at the moment untestable but it really plays no role in the present discussion. We don't know where life started but it doesn't really matter because lacking of understanding the exact steps taken does not open the door for supernatural explanations. If there was an ancient theory for creation that was not disproven by modern science you may have some small window to move it into the debate but like it or not every creation story passed down has proven to be nothing more than myth and the includes the Hebrew myth of a young Earth a world spanning flood, language being spread from the Tower Of Babble and on and on. Faith be definition does not require proof but when you have faith in spite of the proof against it you have to ask why you believe what you believe.
