Water has indeed been found in interstellar clouds:

The gas and the water ice particles in such clouds are quite tenuous, but the clouds are so large, light-years across, that the amount of water would be the equivalent of oceans in space.
And other research has shown through laboratory simulations of the conditions in such clouds that amino acids can form there:
