You can see how a lot of people get freaked out by the huge knowledge gap and fill it with religious explanations.
We are still missing a LOT of the basics about how life began.
Life seems to me to be almost like some kind of fundamentals natural phenomenon that is linked to how matter and energy tends towards being organised.
If it's so random that it only occurs when some little clump of carbon based molecules start to behave somewhat logically, then it could be extremely rare or extremely common.
It's also possible that some of the carbon that's scattered throughout the universe is organised and has those building blocks.
I'm not sure that we'll arrive at an explanation until we encounter *very* primitive life somewhere else
