so, first you have to pin down the meanings of "you" "know" and "exist". Let's say that we agree on the first two words... and only need to question "exist". If "exist" can include times that you don't have a body, then I think we can answer the question. You know you exist, because you can ask the question. If you didn't exist, you couldn't ask the question.
Yes you do exist ,its just that they don't know you do
large colonies of bacteria know to exist in
vampires don't exist. werewolves don't exist. didn't you know that?
I know I exist, and you know you exist, and I know that you know you exist. Thereby we each both exist, and thus from all perspectives, yes, I exist. Sure I do. But, meh, why is this question here?
No, they didn't exist.
We don't know. For all you know I might be a figment of your imagination and so might this answer. OR... I might be imaging you exist...
You don't know. You can't know, because they don't still exist. The Illuminati was disbanded and hunted down in 1785.
if they are more advanced than us and if they exist then most likely but it is hard to know for sure.
i have no clue why they exist but when u get a snswer let me know.
We do not even know that God exists, and this is just a matter of faith. We therefore can not 'know' that angels, the biblical messengers of God, exist.
There may be. I do know that ligers exist. So do white tigers. Probably do not exist in the wild.
We have microscopes.
