You won't find the report in science.
No equations...no experiments....
If you can't believe the report of elders, past or present....
you won't find your faith there either.
Then there is simple straight forward logic.
Someone had to be first.
A thought ...a feeling....sentience.
Ask then which came first..... intelligence or substance.
If substance rules...you are the sum of your chemistry, nothing more.
Spirit first...then you might have a shot at continuing....
after your last breath.
By definition substance must come first, because to have intelligence we must have substance.
We are nothing more than complexly firing action potentials, which is just the movement of charged particles.
We know this so much so, that chemistry can change the way a person is, the way they act, how they perceive things, when they feel good and bad, funny and serious. Chemistry (i.e. pharmacology) can manipulate this by knowing how the physiology of the brain works.
So i can only say that substance came before our intelligence.
In the beginning, there is no need for intelligence. But besides that, it is difficult to define intelligence, are we intelligent? is a monkey intelligent? is a rat intelligent? is an fly intelligent? is an amoeba intelligent? is a cyanobacteria intelligent? is a virus intelligent? is DNA intelligent? is water intelligent?
If you say we are the only intelligence, then how is it that monkeys can perform problem solving? I would call a monkey intelligent, what about a cave man?
And i will be the sum of my chemistry, because if i was anything else it would break the laws of physics and Science, and i could not exist.
