Atheist, do you believe in destiny or predeterminism?

I do and I think of it as an on going chain reaction to the big bang. If we could pause time (hypothetically) and could track every participial and how they interacted with each other, we would essentially know what was going to happy before it happened. Think of it as a pool table with no holes and the ball never stopped; the big bang would be the initial hit, and the ball would go on for ever and ever. Now if we paused it and traced the balls; measuring the angels they bounce, and then measuring the result of that, we should be able predict the on going out comes before they happen. Meaning, that these particles ( billiard balls) are predetermined to an outcome that they really don't have any control over
