there is no evidence that all life came from nothing.
Nobody said it "came from nothing". Once again, you articulate your thoughts poorly.
What IS a foregone conclusion is that it arose from nature via physical processes that require no magic or divine intervention. The evidence for this comes in the form of every observation we have ever made and every bit of evidence we have ever collected. These all show us a deterministic universe that follows natural laws.
We know the Sun is 5 billion years old. We know the universe is 13.8 billion years old. So, at the point where there is our sun, there was once no star at all. As all the evidence we have ever collected shows us a deterministic universe that follows natural laws, we look for and hopefully come to understand a natural explanation for star formation.
Now, apply the same process to abiogenesis. Do you propose magical events to explain star formation? No? Then why would you do the same for the formation of life? Religion, of course. This demonstrates a silly double standard that arises purely from superstition and fetishism.
