And of course they're are people who know more than me.
Again, in theory, we could share a common ancestor with an aquatic humanoid, which branched off and evolved separately, but we have a enough knowledge to know that it didn't happen that way...
Just look at the fossil record (the most solid evidence for evolution): To the best of my knowledge, there have been no transitional fossils found that indicate a land to water evolution occurred. That is evidence enough.

There's no transitional fossils for 1000s of species including us until very recently.
It's also pretty hard to dig up fossils from deep sea beds. I know the ocean has moved, some deserts used to be oceans etc etc but not all dead bodies become fossils. If they are intelligent they may have some burial ritual like us, these bodies may have been sunk in deep ocean trenches, who knows?
I don't care if you don't believe, everyone is entitled to their opinion. But for gods sake let other people believe whatever they want. It is possible, perhaps not very but it is certainly not impossible which I'm sure you know in the back of your mind, plenty of things that have been called impossible have happened or been proved in modern times.
It is the very naive man who writes anything off as impossible these days.
