You are still young I guess. You will mature.

Just a little thought for you: Imagine you were born 300 years ago. Would you be as sure about yourself as you are now?

Of course you would be. You would be wrong, but you would be absolutely certain you were right.

As you mature you will realize the world is not as simple as you think.

Knowing the truth is not possible.

You are acting like a creationist. No real scientist would talk like you do - they would be humbled by knowing just how often they were wrong in the past. They would only strive to learn, they would never be certain they own the truth.
