do we exist?

[nik0tine]

Of course we exist. To think otherwise is absurd. The fact that we can even think about stuff like that proves existence, even if we don't exist in the way we think we do.

I exist, but how do I know everyone else isn't a figment of my imagination and they disappear when I don't think about them.

I have thought about this before. It is strange to think that other people, places and things exist when they aren't in my mind.
