"What is the purpose of Existence in three sentences"
1. The purpose of life is a decision to be made by the individual.
2. Do what you want, as long as it doesn't hurt others.
3. Try to be kind.
You can't deny the fact that universe acts in harmony,
Nope, the universe DOES NOT act in harmony. Apart from Earth, the rest of the universe it basically lumps of cold, lifeless, ugly rocks, or balls of gas. Why would God create such useless and needless objects?
You believe in science, so you believe everything relates by series of equations.
Equations? Sometimes, yeah. Science uses the scientific method. Ever heard of it? You look at facts and evidence, and make a theory to explain the evidence. Then you test the theory.
A theory is falsifible. That is what science is all about. Testing, logic, and explaination.
Science does not only use equations. It uses fact, theory, and logic.
Why wait for someone to come up with the unified theory, while us being here and the universe working in harmony points to the fact that it exists.
The universe does not act in harmony. 99.99999% of the universe is useless. One day, the universe will be pulled into a BIG CRUNCH by gravity, and will end. That's not harmony.
You are acting like a dog locked up in a room. Someone pushes thru a slot to him food and water. The dog has never seen his owner so he doesn't believe he exists, although the food and water do not miss a day, and majically his room is cleaned up while he sleeps....
UMMM. I work to put food on the table. I clean my house.
You say that God is all around us, yet he is strangely absent...
I just be like the bumble bee. The bumble bee doesn't ask why she collects all this honey just to die tomorrow.
We are humans, not bumble bees. We are capable of rational
thought. A bumble bee does not contemplate the meaning of life. We do.
