So, ask yourself one question. Why are you here? Why am I here? Why is anyone here?
The truth is simple to understand. You are not here. You do not exist. You are a figment of my imagination. You exist because my mind is bored and needs friends. That is all. You are less than the worthless speck of sputum that escaped the last time I barfed! You are nothing but a figment of my warped and bitter imagination. Obey me! Obey my every whim or I will think you out of existence! I will de-imaginate you, your entire family and your pet dog too! Obey Me!
Solipsism is the theory that one is the only being that actually exists. This is based around the theory I think therefore I am. Now I know I exist because I am thinking, but how do I know that anyone else exists? The answer is, I don't know that anyone else exists. "Ahhhh..." I here you say, "but I exist because I am talking to you!". Well actually, no, life isn't like that. You see, you may actually be a figment of my imagination, so your protests are irrelevant. Now, if you can't prove that you exist, then you can assume that you don't exist. After all, if you did exist, you'd be able to prove it would'nt you? Therefore, it's safe to say that I am the only being that really exists.
If I am the only being in existence, then I must be God! I am your God! Obey me!!!
