there is no air in the bottom of the pot, so where do these bubbles come from?

The bubbles contain vaporized liquid (whatever it is you're boiling.) They are not air bubbles.

the air bubbles appear when it's boiling because the heat increases the pressure in the pot/pan effectivly removing the hidden air

When the temperture is high, the solubility of gases in liquid is lowered, that's why the dissolved gases have to leave the liquid. This is also the reason why there is more dissolved oxygen in cool water than hot water does.
Note that solubility for gas is lower when temp increases. And the solubility of other solutes is higher when the temp is high.
