There is no when, time is an illusion created for your comfort
The past did not happen, only the present is real

The present is held together by the glue of my mental strength.

No really, why do everything exists?
What's the idea behind existance?

What do you mean "No, Really?"
Do you honestly think that anyone on an internet message board based around an independently developed video game is going to know the answer to that question?
Do you honestly think anyone on earth would be able to give you any kind of useful answer?

It's a stupid question.

This week on DRLFF, Asklar and Metal Chao talk about the meaning of existance.

What if we're all just oranges? Oranges that are making this all up in their collective hivemind?

The fact is that anything we perceive as "existing" is only defined by arbitrary boundaries, including mathematics which is the most universal language we have. The problem is how we can count real objects when we have no accurate definition of one thing ending and another beginning? If I have three stones, how can I prove where the boundaries of one stone and the next are? Our entire perception of reality as we "discovered" it, is in fact based on an assumption we "created" in response to what our senses have told us. We can never truly understand existence because our senses do not cover a broad enough scope to be able to understand it, so until we evolve the ability to perceive anything at about 10^-23 metres, that question can never be correctly answered.

Woah man, that's deep.

That's like responding to a facebook poke with a MIRV.

School be started. Me tired.

Roast you are probably the [INSERT AWESOME ADJECTIVE HERE] people on DRLFF.

Everything I learned in and about philosophy can be boiled down to this:
Your perceptions are merely that: you cannot be absolutely sure that you see reality (see: insane people)
You cannot tell that there are other sentient people outside your own consciousness (see again: insane people)
You can debate and whine all you want about philosophy but beyond these points is all belief, not logic.

Not only can you not prove that what you see is real, but you cannot prove that there is a reality at all, or indeed anything. Proving yourself is debatable, especially as you might well be attempting to prove it to people who do not exist.

So in other words, its more than likely one of us is just having this extremely meta discussion inside their head.
I vote for collective orange consciousness.

The only thing that you can be certain of is that everything you perceive exists, in a way. Either it does, or it does in your head.

And Nicolas, no, just no.
