When we are born our consciousness, our "soul" is formed, and before we were born we did not exist, we were in a state of non-being, of non-existence, after which something is formed.

This means that when we die, we will pass to another state of non-existence, and by logic, if from nothing we arise, if from nothing we are born, then when we cease to exist we will pass to exist again.

The same thing happens with the universe, we all know the big bang blablabla, before it there was absolutely nothing and suddenly existence arose, then when the universe itself dies it will arise again from nothing.

This is pure mathematics, if something exists from INFINITY years ago, it will never end
