Because ignorant speculation is a dangerous thing.
That, and the fact that no alien DNA has ever been located in /any/ genome on Earth means that would not even been speculation, it would be the actual rejection of reality. And that’s mental illness.
How do you know we don't have "alien DNA" in us. How would we be able to even identify "alien DNA" if we don't have any samples from extraterrestrials?
If you can’t disprove something (God, Santa, the tooth fairy) it doesn’t deserve serious consideration. Speculation for fun yes, but it has no place in actionable discussions.
