Everything exists because either a). It always existed b). It has to exist c). It wants to exist.

None of these necessarily contradict eachother for example a + b = c or b + c = a, or a + c = b.

But they also seemingly contradict eachother in the fact that if b). It has to exist then c) wanting to/having a desire to is irrelevant. Or if a). It always existed... then b) it has to exist is redundant and c). wants to exist is also redundant as there was never the choice not to want to exist because it always existed.

So which is the right answer?
