Do aliens exist??

Ok so there are at least 100 billion stars in each galaxy, and there are at least 2 trillion galaxies in the universe.
That’s 200 sextillion stars in the universe (200,000,000,000,000,000,000,000).
Each one of these stars has the potential to have planets which can foster life.
And these are conservative estimates.

So the answer is YES, they exist, and quite honestly it’s kind of a stupid question to ask.
