Apart from the ghost some people reportedly see and some flying saucers in the sky, are there any other living beings that may exist and Humans are unaware of? How sure are we they aren't living amongst us?

no they don't........what they call aliens are demons

Aliens
scientific Fiction

Unless in outer Space

Ghosts exist in the same realm as pink unicorns and righteous Nigerian pastors. Simply put, they do not exist. There is no evidence for their existence whatsoever, and nothing we know about biology suggests the existence of any alternate conscious being that emanates from human bodies after death.

On the other hand, there is a high probability that aliens do indeed exist. And by aliens, I mean alternate life forms similar to ours. It is estimated that there are 10²⁴ planets in our observable universe. That is 1,000,000,000,000,000,000,000,000 planets! Accordingly, it is childish thinking, and just statistically absurd to think that life exists only on this one we're on. If only 0.0000001% of planets have life, then that leaves one thousand billion planets with life. That's 1 with 15 zeroes!

The unfortunate thing is that we might never find out for sure in our life times. The laws of physics apparent within the universe limit the possibility of travel through the enormous distances that exist between these potential life-holding planets. Sad really.
