How much do you think you could know about the world if you never trusted what anyone else told you, or anything that you read?

How much do you think you could know about the world if you never trusted what anyone else told you, or anything that you read?

I think that I would not know much about the world, because there is no way I can know, unless I myself go to the place to experience everything and see it for myself. However, I am not omnipresent, so I will not be able to know everything that is going on at the exact moment. So there is already a lot that I do not know about the world. Because of this, I will only know what I see in front of me. There can be a huge accident on the other side of the world, and I would not acknowledge it's happening simply because I was not there to see it. However, it has actually happened because others have seen it.

Also, I would not know anything about the past, because I was simply not living at that time to see and experience it. So if I do not believe what anyone else said, that means that I would also believe that the world came into existence as soon as I was born, since the past does not exist in my thoughts. So if I don't believe things that are written about the past, that means that I will already not know a lot about the world because I will not know what has happened before my time.

If I am truly 100% skeptical, then I would be very narrow in perspective, and I would not know anything else that is going on outside in the world. I would have a very small perspective on everything, and I would know nothing about the world. I think I would know less than 1% of what is going on in the world if I did not trust what anyone else told me, or anything that I read.
