Cells divide and make new cells, is all life on Earth rooted in one super ancestor cell? Or are there parallel paths to cell creation?

Sure. I agree that it’s a very hard proposition, but I’m sure scientists thought going to space was a hard proposition before we did it. Photographing the black hole at the center of our galaxy was a hard proposition until we did it.
Our collective incredulity doesn’t seem to have prevented science from overcoming seemingly impossible feats, thus far, and it’s that relentless desire to explore and discover that leaves me thinking it’s more likely that we just don’t know these things yet.
There’s a difference between a hard proposition and something being within the realm of possibility. There are some things that we will never be able to know for certain, and this is one of those.
Hell, the cells that we all evolved from might not even be the first life to form on the planet.
It’s not a subject like astronomy that better instruments will be able to improve our knowledge. This is a history question, not a scientific question, and you can’t answer those questions if evidence doesn’t exist.
