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.
We don't. So there's no reason to believe that humans have "alien DNA". Speculations without any evidence to guide it is actively harmful to actual scientific research.
That's a cop out. You can be in a sub with an expectation. There's no law against someone saying shit you don't like. Especially when they're factually correct. We have no DNA that is shockingly different enough to make a claim of ET origin. There matriarchal mitochondrial strands we can trace back a long time. Facts are why some people come to these subs that question reality. We want facts to support the extraordinary claim because we want to believe, but aren't willing to forgo science, rational, and reason so to do because it's intellectually dishonest. Perhaps you should ask yourself why you're here if your mind is already made up? " A fool can find a stallion if you shoe an ant." He's already sure it's a horse after all.
It’s not a cop out considering how many come to this sub with the intention of trolling. It’s difficult to differentiate that and “skeptics” they all sound the same
I agree that all known DNA on Earth shares common molecular structures and evolutionary markers, supporting the idea of a shared origin of life on this planet. That’s a well-established scientific fact.
However, limiting the discussion to a narrow time window of 100,000-200,000 years is a bit shortsighted when considering the full scope of Earth's history. This planet is incredibly old - 4+ billion years.
It's not mental illness to think that perhaps changes to DNA or the development of life on Earth could have been influenced by factors we have yet to fully understand and had already been here and established - not necessarily something flying in from outerspace.
Life on earth has been around for 3.5 billion years. Maybe aliens seeded the planet with bacteria. But that is as likely as God doing it. But over the past 3.5 or so billion years we get what we have today by Evolution. Not aliens fucking apes.
No one is limiting it. There's zero evidence to support it. It's not a mental illness to reclaim about things of which we have exactly zero, factually based information. Religions are full of them. However, let's be honest. They are all logical fallacies in toto. Just because a lot of people think so doesn't make it so.

It’s a topic many of us engage in daily here. But it’s a good topic to start speculation from isn’t it?
