Does this world exist

Answer 1

We cannot be certain of the existence of this planet. If you see something you think it is real, therefore you believe everything other people tell you is real as well. Now, think about this. What if, you were imagining those people? What if this stuff you see is in your imagination?

The only way to be know that you yourself exists is to think "I think, therefore I am." If you can successfully think that without hesitation on the first time then you can be certain that you are real and that you are not being dreamt up by some random person. But, is everything in the world there because you see i, or do you see it because it is there? YOU DO NOT KNOW! What you do know is that YOU exist. Remember that, but forget the idea that everything exists and it is a lovely happy world! It isn't and it doesn't.
