1. It is neither prime, nor even. It just decided to pop out from somewhere and confuse everyone studying numbers. Very unpredictable.

My opinion on the most random number:

The smallest number that has never and will never exist in the universe.

The moment a number is written out, calculated in a computer, or counts the atoms in the universe, it's no longer random. It has some reason to exist.

Contrarily, just picking some massive number with a bajillion digits isn't really random. It's just a big number.

Thus the most random number would be the smallest number the universe will never know. It's going to be incomprehensibly large, near infinity. Plus, you'll have to wait until well beyond the heat death of the universe for the point that the entropy of everything equals zero.
