I happen to know the answer to the three most important questions, they are "How did the universe come to exist and did it always exist?", "What should be the goal for all?", and the special scientific one of "What happens after death?". Two of these questions can be answered without anything but bare reasoning, but the death question, however, is only answerable as a result of facts gained through scientific study. That is why I'm focusing the point of this thread to be on the death question.
Before, I didn't use links to certify my statements, I didn't explain my statements in a clear and understandable form, and I assumed that whatever I typed was going to be right. As a result of learning from trial & error, I will now present my hypothesis on what happens after death with the intention and the hope of others rigorously analyzing and constructively criticizing it's nonsensical parts. Now, without further ado, please allow me to present my argument.
What happens after Death~The Finale
The universe is roughly 14 billion years old. The possibility for basic lifeforms to form naturally under ideal conditions and within 100 billion years is at least 1 in 10 to the 67th power. This proves it to be unreasonable to believe that this current universe is the only one that has ever existed since it contains lifeforms that should need much more time to develop than the universe's age has allowed.
This strongly suggests that this current instance of our universe is not the first one and there's no good reason to believe that it will be the last. Therefore, there is still a lot of time, if not an infinite amount of time, for life to develop again.
Now, I think I know what you're thinking, how does all of the above relate to what happens after death. Well, you're conscious right now. So therefore consciousness is a possibility because otherwise you couldn't be conscious right now. It doesn't matter how you are conscious, just the fact that it's possible is enough because given infinite time, all possibilities will almost surely happen again.
So since it's obvious that the universe has had many instances of itself previous to the one we are currently living in, that also means that it most likely will have many instances of itself after the one we are currently living in. Furthermore, since for the most part, energy & matter is conserved, never increasing or decreasing, whatever it is that allows you to be conscious, will be there in the next universe, and the universe after that, and so on ad nauseam.
So, your consciousness arising will always be a possibility, and as a result of the fact that you won't be waiting to be consciousness again since you're not alive, as soon as you die you will be instantly placed in the moment in time when you are consciousness again.
Alright, let us perfect this hypothesis so give me all your constructive criticisms.
