There were photosynthetic organisms before there was a water cycle?
But of course!!
The water cycle is completely dependent on the existence of biological organisms!
Without them, the sun cannot warm up water on Earth and it will not turn to steam and clouds and cool down and then fall back to the Earth.
Biological photosynthetic organisms convert the sun's light into warmth, didn't you know?
Haven't you ever noticed how you turn green when out in the sun?
