I think spiders and all insects are bio-mechanical robots sent here by extraterrestrials to spy on us. Look at them, how they move, how do they move, what's inside them? They're cameras and we're the entertainment. No creature needs 8 F'ing eyes. Earth is the 'Real World' to some advanced society on another planet.
As a matter of fact what am I talking about? I think we're bio-mechanical robots. Robots I tell you, artificial intelligence. What's the difference between flesh & blood or metal & oil. We fall apart, make hospitals to "repair" ourselves. We even replace parts when they don't work anymore.
We have no souls and we're all gonna die.
