How does science explain gravity if we don't know why mass attracts mass?

So I know that we can not explain why objects with mass attract other objects with mass but what is the current theory,I mean how science explains it?

Welcome to PF!

The best theory to date is General Relativity (GR). It describes gravity as a geometric property of spacetime where spacetime tells objects how to move and objects tell spacetime how to curve.

However, there is a gap in understanding between GR and Quantum Mechanics (QM) that is an active research area. Many physicists are trying to unify the two into a more comprehensive Quantum Gravity theory.
