If heat is energy, why isn’t it possible to genereate electricity out of thin (warm) air and by that cooling our atmosphere while generating (nearly) endless energy?

Energy naturally flows “downhill” – a hot object will dump heat into a cold object, but the reverse will never happen.
If you have hot air and want to extract energy from it, you need to provide a lower energy place for the energy to flow.
There is no low energy place available to do this. The inside of the earth is even hotter, and the cold vacuum of space is gravitationally unfavorable and too far away.
