Have you ever wondered about our existence?
Have you ever wondered about our comprehension of things, why we even understand anything at all?
Our purpose of living? One's purpose of living?
Why homo sapiens becomes intelligent faster than other animals?

I'm sure, that some of us has given them some thought, but didn't go deep.
Some of us, just couldn't give a damn to think about it.
The rest like me, will donate a lot of our time, to prod about this.

Majority of the human race (90%) would baselessly point towards the existence of a supreme being. Because the mystery of our existence could not be explained scientifically.

I do not think that way. The theory of creation and the existence of a god isn't appealing to me, it doesn't even look logical to me. I've met people who tried to convince me in this, and I was, too, happy to listen. He presented a very strong argument, which is why the laws of physics are that way? Why is it that there is a law of physics, that every particle in the universe obeys? There must be someone to organise it. He then used a piece of paper to show me, "the words and letters are arranged properly, isn't it logical that somebody HAS arranged them?".

Well he has a point, but that surely can be explained in the future, has something got to do with the super-symmetry breaking down into the 4 forces.

Then I posed a question to him,
I asked, "If God created this world and everything, who created him?".
He answered, "God is just BE, he has been always there."
"If He just BE, why can't the universe just BE too? If God created us, someone must have created God, and that someone who created God must be created by another person, Right?"

He couldn't provide me with a reasonable answer. Currently science is also unable to provide us with a satisfactory answer.

When will we get the answer? Will we be enlightened about life itself after that? Can the meaning of life be written down in a mathematical equation? Will it make us better people after that?

Only time can tell, no?
