How did the Universe begin?
With the first primordial perceptions. And it grew more complex and organisms grew more complex tools to perceive.
What is the Universe made of?
Light patterns on our eyes, nerve tingles on our fingertips, soundwaves in our ears, chemical reactions on our tongues and in our noses.
Is there free will?
It sure as hell feels like it. But we are just a ping pong ball, dropped into a sea of billions of other ping pong balls and mouse traps. We are at the forefront of our trajectory, so it feels like decision-making. But we are simply a product of where we are dropped and what we bounce off of.
How do you find truth?
There is no truth, no objective reality. Reality is simply a product of perception and the truth we see is subjective to our vantage point.
Who or what is God?
A great tool to control the masses. A great excuse for war. A distraction from much more important questions.
