If aliens visited the earth, why are they hiding from us?

Affirmative, aliens have visited the Earth in some form.

By alien, I mean any kind of alien most likely a single celled organism. Aliens are probably crawling on your skin or inside your digestive tract right now.

Yes, but you have no evidence that life is of Earth origin. Either A. Life is all of Earth origin. B. Life is all is of alien origin, panspermia. Or C. Combination of both native and alien. The problem is how would we differentiate between alien and native?

You have no evidence that life on earth is from a martian origin.

Nor do you have evidence of a bacteria that fits your description.

I am of the theory that humans are of Martian origin. Thus humans are aliens to Earth.

"Perhaps life did not begin on Earth at all, but was brought here from elsewhere in space, a notion known as panspermia. For instance, rocks regularly get blasted off Mars by cosmic impacts, and a number of Martian meteorites have been found on Earth that some researchers have controversially suggested brought microbes over here, potentially making us all Martians originally.

I'm alright with the spam. First, all living microbes may be of alien origin. In the sense that abiogensis did not occur on this planet and that abiogensis occurred on a different planet and that arrived here. Second, life is durable there is bacteria found on Earth in the most unlikely spots and sometimes even multi cellular organisms.

Third, we haven't examined every microorganism. There could be an organism made up of an alternative to DNA inside your body and you would never know. I'm thinking that Mars once had life. That aliens microorganisms from Mars are on Earth now.

If living cells from an entirely different evolutionary existence were to show up on earth we would know about it, mainly because the chance of cells using DNA or RNA as an instruction carrier in two separate evolutionary origins is improbable, we know all cells we find are of earthly origin because they all use a DNA and RNA nucleic code system with a 3 letter to amino-acid to protein registry, find me a cell that doesn't use these systems and you may have a case.

Also where would these cells have come from? its highly unlikely that even deactivated cells could survive interstellar trips, let alone thrive in a environment that may be completely alien to them.

There is a good chance aliens are on the planet right now. Said aliens would be microscopic and would have travel via meteor. Perhaps the asteroid that exterminated the dinosaurs carried these alien microbes. The main problem would be recognizing said aliens. See Bill Nye's Evolution undeniable for more information.
