Of course not. That's stupid and overlooking the obvious facts that humans and monkeys are related in the same way as dogs and bears. It is not a linear evolution. Close, but no cigar. Humans must have evolved from something.
Evidence seems to point to an ancestor common to ancestors of apes and other primates.
Not the little green men of Orson Welles, nor the conspiracy theories feeding the cultural x-files. In fact, no aliens in recent history. The aliens in my theory make a few visits to Earth. The first is several million years ago, when they begin a grand experiment on one of the more advanced creatures on the planet. Thus we have a jumpstarted evolution.
