This is a philosophy movie

So everything you just said is a lie? Got it.

Also, lying is never part of any 'human situation', unless it protects someone from physical pain or death (a very rare situation).

HUMANS do not lie. The two-legged half-animals that populate THIS planet, do lie.

There is a cosmic-size difference.

You're kind of contradicting yourself..

"You don't understand the human situation"

So according to your "Every sentence is a lie." statement, you actually lied, and you really mean "You do understand the human situation."

"We lie".. so because you lie, this means "We tell the truth."

"Everybody lies" .. so being a lie, this means "Everybody tells the truth".

Which is a lie, because a BODY can't do anything, it's the SPIRIT within the body that does things. Therefore, "Everyone tells the truth" would be more truthful, however, anyone that has lived in this world among these... creatures.. of this planet, should know that there are plenty of liars in the world (as your post proves).

Every sentence, however, can't possibly be a lie. This type of thoughtless statements often become paradoxes as well. If 'every sentence is a lie', then it's the same as saying 'This statement is a lie', which, if true, would mean it can't be true, which means it has to be true, aagh.

In the end, your post has a few incoherent, self-defeating, thoughtless, paradox-creating non-statements that offer no value, insight or usefulness of any kind to anyone - besides possibly mild internal snicker to yourself.
