Our hominid ancestors split from their ape relatives about eight million years ago. Given that we have evolved from such a source, it's equally possible that other orders of life have evolved towards intelligence that equals our own--or surpassed it, indeed, given the age of the universe and the number of chances for a new start for the evolutionary process.
So it's better than remotely possible that some of the alien races we'll meet in future--when we enter space properly instead of just playing in our own back yard--will be the remote descendents of reptiles, amphibians, birds, et. al., just as we were once related closely to apes.
One of the early Greek philosophers said that if cattle could worship a god, they would give him horns...Given therefore that religious imagery is usually anthropomorphic to some degree, what would be the nature of the gods who these folk worship, and what legends or holy books would they have to show us?
