Rules for Atom particles to bind?

Question

What are the rules for 2 atoms to bind together?

Reason why i ask this question is because me and my friend got into an argument about what was first, ice or water.
And my friends argument was that atoms don't bind in cold temperatures.
I believe ice was first, and due to the planet earth not having the ozone layer yet, the cold from the universe would freeze anything, including the 2 hydrogen and one oxygen atoms

So my question is, can atoms bind into molecules in cold temperatures?

You are so confused, dont even start.

Short answer. Yes atoms can bind in cold temperatures.

But the early earth was hot, and this wasn't anything to do with an ozone layer.

The water on earth came mostly from comets that hit the earth in the first few hundred million years. The comets were made of ice and rock, but the ice boiled in the heat of the comets collision with earth, and  became steam, then as the earth cooled the steam turned into water as rain.

Before that the ice came from the hydrogen and oxygen in the interstellar nebula, and it would have been in the form of vapour. that the sun came from, and before even that the oxygen came from the interior of an ancient star, and the hydrogen came from the big bang.

You are both wrong. Hydrogen came first, then oxygen, then water vapour.

... which then formed ice, and once it ended up on a planet, and the pressures were right, liquid water could form.
