[Serious] Why I consider Atheists the Dumbest of the Dumb

[Mister Agenda]

Sigh. New flash: Atheists (and materialists) are aware that consciousness, mathematics, electricity, wind, etc. exist. Do you think it's possible that you misunderstand the materialist position?

The definition of something immaterial is without physical form. That's what I learnt anyway. 
Air, space, time, neither of these even come from something with a physical form

So you do misunderstand the materialist/physicalist position. Roughly, all that exists is matter, energy, space, and time. Concepts only exist in physical mediums, like brains. All the things you describe fall within those boundaries. Air might be immaterial for purposes of walking through it; but it's not immaterial in the sense that it is not matter, energy, space, or time.
