Ik this might be a difficult one but I genuinely want to wrap my head around this

Easiest way to put it is, imagine space as a grid of squares all throughout, like a math notebook, but in 3d. With all perfectly straight lines.
When an object has mass, its existence in space curves those lines and twists them, making them longer and not straight anymore. And since the shortest path from point A to point B is a straight line, any curvature of those lines makes for a longer trip. And the more mass an object has, the bigger the curvature of the lines, and bigger effect it has.
But those lines arent only space, they are spacetime. Affecting both space and time. So if the line is longer, you will travel further and it will take you longer time to go from A to B.
So to put simply, gravity is the property of mass to curve spacetime.
