The main thing I noticed was that when you watch the astronauts
playing with liquids and what I noticed was that the liquids would
ball up together into a ball. and that the larger clumbs would draw
the smaller ones into it, if they got close enough to them.
​
That's caused by surface tension, not gravity.

which I knew back when I was a kid. so sence we don't really know what
in space is cousing gravity on mass objects then can we still say that
gravity is a force of energy ...
​
No, we can't. Force and energy are two different things.

Well, when you drop something, the force of gravity accelerates it downwards: this has the effect of turning its potential energy into knetic energy (which is dispersed as heat (also energy) and sound (more energy) when the object hits the ground).
​
The gravitational force doesn't make energy: energy is conserved. The action of gravity turns one sort of energy into another.
​
I hope this answers your question: I wasn't quite sure what you were asking.

Therefore IMO the EP is conceptually incorrect and therefore the GR is also incorrect.
​
You should write to physicists about that. Make sure that you write your letters in purple ink, to let them know you're serious.
