How many galaxies are there or do we not know yet ?and also r aliens real or no?

We do not know yet

Explanation:

No one, not anyone has explored all the galaxies so we dont really know.

Aliens are possibly real bit it is most likely no, because in The Bible God says he created humans. not a single thing in the Bible says that aliens are real.

their are two trillion galaxies, yes aliens are real ufos and aliens are real

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
