In that specific chain of events, you starting the car is the first cause.
And not, for example, my filling of the gas tank?
Nope. It has a chain of causes.
Not a chain: a network.
True.
True again
Exactly.
A chain of events all tracing back to you pushing the button
Not all of them. The gas needs to be there and that isn't from my pushing the button. The air needs to be there and it also isn't from my button push.
I didn't claim this is the only cause, rather the first one.
Before it, there were billions of billions of causes that led you to press the button and so on.
Eventually... in the history of all causes of everything, there was one cause that started the entire process.
Why was the first the one that started everything after? Why not other 'beginnings'?
Imagine a tree growing while each leaf is a cause....
Until the point it "shrinks" back.
Why would there need to be such a shrinking?
How so?
And what started this entangled network? it was always there i assume?
It was there whenever there was mass, energy, time, and space.
