Sometimes when people's mind wanders freely they come across the question, "Is it possible that my life is just one big dream and that nothing really exists?" It is very possible that we are all living in one big dream. Everything around us could just be an idea in our mind, which makes existence seem real. I believe that this is quite a pointless question to ponder. Whether or not we are a dream and whether or not our existence is real does not matter. We are all living a very real life, breathing real air, eating real food, having real jobs. Why does it matter if it is a dream or not? I believe it is all very real and that there are ways to prove that other things exist in the universe besides yourself.
I feel that the number one way to prove existence is through our senses. I believe that if you can see it and touch it, then it is real. When thought through logically, no one person can deny that if something is unable to be felt, seen, smelled, or even heard, then there must be no existence of it. It is simply nothing. This may turn into an argument of faith and of God. I am not denying a God simply because He is unable to be seen or touched. God is in a different realm I believe. So, for now, I am concentrating on the existence of earthly life. Being said, I think it is absolutely true that something does exist if you can touch, hear, smell, or see it.
However, our senses may sometimes deceive us. One may simply argue that we exist without backing that up with any proof. Well I believe this to be a valid argument in that it is defended on the grounds that if we do not exist at some level, then there is no way we can know that we don't exist ...
