Please explain as soon as possible. Give me the source.

Thank you everyone so far, but could calcium exist naturally as gas?

Calcium is not naturally found in its elemental state. Calcium occurs most commonly in sedimentary rocks in the minerals calcite, dolomite and gypsum. It occurs in igneous and metamorphic rocks chiefly in the silicate minerals: plagioclase, amphiboles, pyroxenes and garnets.

Calcium is not naturally found in its elemental state. It occurs in rocks such as calcite, dolomite, gypsum, etc.
At STP (standard temperature and pressure), calcium is a solid. The melting point is 842 degrees Celsius, so it would not appear in liquid state on any planet in our solar system (even Mercury at noon isn't hot enough to melt calcium).

it exists as a solid. I don't have a source but it's obvious because milk is a good source of calcium right? Well that's why milk is so thick unlike water.

As a solid, mainly CaCO3, which is limestone or marble. If you seek the source, look about you.

Does not exist by itself. It exists in other forms such as CaCO3.
However, at STP it would be solid.
