Just Wondering...

Since water covers the majority of the earth's surface, wouldn't it have made more sense for sentient beings to evolve in an aquatic environment? Or is evolution a form of survival not only for advancing organisms, but for their descendants as well? Forcing life to reach new areas in an attempt to preserve previous generations that provide stability in our ecosystem?

Whenever I try thinking about it...it always feels like intelligent design in the end. It would be incredible if this was a natural course for life to take, but even that first cell must have come from somewhere with some behaviour written into its DNA. Seems unlikely that so much can come out of nothing.

Why? Sentient life is not some goal of evolution, it's just one adaptation that happened to be useful for one particular species... and that happened to be a land-dwelling species.

As it happens, dolphins are one of the next most intelligent animals on the planet, after the primates.
