Are you claiming that humans and trilobites existed coincidently?
Call me crazy, but it wouldn’t surprise me to find out that they did. Science thinks it knows quite a bit more than it actually does, as we find out from time to time.
Of course, no one expected to find out that elephants, golden moles, aardvarks, and tiny elephant shrews were phylogenetically closely related until we were capable of actually running and reading the DNA -— SURPRISE!!!
Who says God doesn’t have a sense of humor!!!
