Do you need a purpose to exist?
I, personally, don't need a purpose because I have already fulfilled it. My purpose is to live my life and have nothing stand in the way of it. Not all things need a purpose to exist; however, we seem to have one anyway. This topic is actually quite hard to cover. It is all based on what a person thinks and believes.

Do you need a reason to live?
Nothing needs a reason to live. Anything can actually live if they are given life, but that doesn't mean they need an exact reason. I don't need a reason because it's almost the same as purpose. Reason and purpose are almost the same thing.

Do people need to know who you are for you to exist?
There is an obvious answer to that question. The answer is no because there are things we don't even know exist, yet they continue to exist, it's just that we don't know about it yet. However, we can think of it as non-existant because we don't even know its there. So there is a 50/50 on this one depending on the person's beliefs.

Can you live with being a nobody?(Not KH Nobodies)
Of course I can. I think I'm a nobody to everyone. I'm sure many people do, and they continue to live regardless of being nobodies. There are some people though that do anything for attention, and those people I don't think can live as nobodies.

Can you exist with being ignored by the masses?
I think I sort of answered this with the above answer

Do you need recognition to think you even reside in this plane of existence?
This one is a toughie This one depends on the person's state of mind. If they believe they are nothing and are not recognized by others, they may actually believe they are not part of existance. It all has something to do with some psychological type of thing, but I don't want to get into that

If you weren't recognized by anyone, would you cease to exist?
Personally, I wouldn't. I don't need recognision to exist. I would rather much like not to be recognized because that way I wouldn't have to deal with the pains and troubles we have today. However, I would be awful lonely, and I hate to be alone.

If your purpose was fulfilled, would you continue to live?
Hehehe like I've said already. I've fulfilled my purpose, and still I live. One does not need purpose to live.

Would you even have a reason to?
Probably not, but if I did it wouldn't be a good one so let's just leave it like that.
