Aliens are all over this planet-
They come from another dimension, far beyond the stars-
They’re the ones that seeded (humans) us here on this planet earth.
They’re probably 1,000,000 to (Phone number can only be seen by the question and answer creators) years more advanced than us !
And they’ve been watching us for thousands of years-
I could go on and on, but there’s so much life out in the universe it’s unbelievable!
They everywhere they exist!

I'm from Phoenix. We have quite the alien sighting chef-d'oeuvre! Reputation. 👽

I believe in Aliens & UFOs. My daughters Mother-in-law (Linda Napolitano) was involved in the most famous alien abduction case in history.(THE ALIEN ABDUCTION OF THE CENTURY : LINDA NAPOLITANO STORY) . Fascinating story. Check out this story and next search for videos about NASA’s James Webb telescope.

Another reason oxygen isn't needed for some living thing: Trees don't breathe oxygen, and this: According to a 2019 discovery by the German Aerospace Center, samples of organisms including bacteria, algae, lichens, and fungi survived on the exterior of the International Space Station for 533 days. More than 250 species of bacteria and fungi can survive in outer space, and some thrive there. Lichens can also survive in space after exposure to UV and cosmic radiation, which is lethal to other microorganisms.
There is no oxygen in space.

Indeed it is healthy to be mindful of our assumptions.
