The earth is a roundish planet orbiting the sun in space and is smaller than a spec of dust in the entire universe. Yet somehow, we're supposed to believe that this molecule of a planet that has been bombarded by space debris (hate to call it that) for eons hasn't had life deposited upon it from elsewhere. That doesn't make any logical sense.
I watch Ancient Aliens...the circumstantial(?) evidence is overwhelming.
I know that I have a hard time believing it, too, but the octo’s and squid’s etc unusual DNA are found nowhere else on Earth. Most unusual. Not sure I believe in AA’s “panspermia” premise, but it’s something to ponder.
