If there wasn’t an atmosphere to provide resistance, there wouldn’t be water vapor suspended in it, there wouldn’t be dust particles suspended in it to provide places for condensation to happen.
With no air resistance, there wouldn’t be rain in the first place.
I took the liberty of assuming there is air, it just doesn’t “move” or impede the process of evaporation.
You can evaporate water in a vacuum, so you could have an atmosphere with no other gasses than water and still get rain. The process of condensation should still work. I think the concept of air gets weird though…
