Have you ever wondered why you are you? Why you were born into this world? Why you have a consciousness? Why you can control your limbs, your thoughts, your actions?
I have, when I was very young. I used to think about all these, and more. Like, what will happen to me after I die? Or, is there life out there? Or even, is time travel possible?
These are all questions that have been asked by mankind since time immemorial... I do wish I had the answer to at least one of them.
