It will have been ticking before the big bang, and how did an atom get there?

Atoms didn't form until after the Big Bang. Time didn't "tick" before the Big Bang because it didn't exist. It's difficult to comprehend but there was just nothing.

What caused it all to start?

A singularity - An infinitesimally small, dense and hot concentration of matter.

In other words, something. Do the scientists know how this matter was formed ?
