Troposphere. This is the lowest section of the earths atmosphere that contains 75% of the earths atmosphere by mass and 99% of the earths water vapour. This section of the atmosphere starts at the surface and extends 7-20km up, the thickness depending largely on where you are in the world.

What percent of earths atmosphere does water vapor make?

0% (at -44 degrees F) to 4% (at 86 degrees F). It's produced from the evaporation of liquid water, and is invisible. Almost all of it is contained in the troposphere. It's the condensation of water vapor that forms clouds, rain, snow, and other precipitation.

Did earths original atmosphere contain methane and ammonia?

Yes, Earth's original atmosphere is believed to have contained methane, ammonia, water vapor, and other gases. This atmosphere was formed from gases released during volcanic activity.
