Well, if you look at it logically, there was a time when the Earth was lifeless. And there is a time now, when it is teeming with life. So, something in between happened. Some people think God was necessary to turn a barren world fecund, others think it might have happened by either chance or necessity of circumstances.
For myself, I'm inclined to think God doesn't show himself to those who don't want Him, and never will. I think He leaves faith an entirely voluntary matter, a love affair between Him and His believers, and that He will never be 'proved' to exist objectively because that would remove our free choice to trust in Him. So, my guess is that eventually, sooner or later, abiogenesis will be shown to be not only a possible, but the most likely proximate cause of life on Earth.
And will that affect my faith? Not one jot. It just pushes the issue back one stage. Who created the circumstances that made abiogenesis likely or inevitable? Ultimately, who created the universe and the mathematical, physical, chemical and eventually biological laws that seem to govern it? Abiogenesis seems an unlikely answer to such questions, and, indeed, does not even seek to address them.
