No, gravity creates a hole in the universe that forces mass into existence. Even in accepted scientific theorems, mass doesn't cause gravity. That's just some bullshit they give Elementary schoolers because none of them are really going to care what actually causes gravity.
Explain? I thought mass came from a ton of particles from the big bang coming together slowly over time to create small amounts of mass, which would then accumulated into larger amounts as the universe was simultaneously cooling down. According to this, I would imagine that gravity is a by product of mass rather than actually creating mass.
At the same time, I think this explanation of 'mass curving space-time thus causing gravity' only explains things on a larger scale, not so much on a small scale. This is also why they have attempted to explain gravity in other ways and have introduced Quantum Physics, correct?
