The reason planets orbit stars is due to gravity. The reason stars glow is due to heat. What's the reason for gravity existing?

There is no reason.

It simply is.

Humans have found 4 forces that control the universe. (there many be a fifth involving quarks but that is still to be proven)

Electromagnetism

Gravity.

Strong Nuclear force

Weak nuclear Force.

Everything we experience in this universe is the interaction of these 4 forces.
