Evaporation
The main processes that return water vapor to the atmosphere are evaporation and transpiration. Evaporation occurs when liquid water changes into water vapor from sources such as oceans, lakes, and rivers. Transpiration is the process through which plants release water vapor from their leaves into the atmosphere. Both of these processes contribute to the water cycle by replenishing the atmosphere with water vapor.
Sublimation is when ice or snow turns directly into water vapor without melting first. This process allows water stored in ice and snow to evaporate and return to the atmosphere without becoming liquid water.
could water exist as a liquid if we don't have a atmosphere
The moon has no atmosphere or liquid water.
When liquid water falls from the atmosphere, it is called rain.
Gas in atmosphere: argon Liquid in atmosphere: water (as rain) Solid in atmosphere: dust

No, water vapor is the most abundant gas in the Earth's atmosphere, not liquid water. Water vapor makes up around 1% of the atmosphere.
Water cycle
The water cycle is driven by energy from the sun. Liquid water is evaporated and changed into a gas. In this process, energy is absorbed (endothermic). The gaseous vapour rises and circulates in the atmosphere, cools and changes back into a liquid. This process is called condensation and releases energy (exothermic). Tiny droplets of water in the atmosphere accumulate to form clouds, which can return the water to Earth as precipitation, namely rain or snow.
The most direct route for precipitation to return to the atmosphere is through the process of evaporation. This occurs when water on the Earth's surface, such as oceans, lakes, and rivers, is heated by the sun and changes from liquid to vapor, rising into the atmosphere.
Water is the only substance that commonly exists as a solid, liquid, and gas in Earth's atmosphere. Solid water is ice, liquid water is water, and gaseous water is water vapor.
