Solve the paradox?

Question

You invent a time machine, and you go back in time and run over your grandfather. But if you grandfather was run over, that means that your parents wouldn't have been born. And neither would you have been. But if you were not born, how could you run over your grandfather? Do you exist or not exist. ADD ON: You invent a time machine, and you go back in time and run over your grandfather with a ford explorer. But your grandfather happens to be the creator of ford, and you ran him over before he could create his company. So how could you run him over if you didn't exist, and how could you run him over with a ford, if ford never existed?

Update:

I know for a fact time travel is not possible, The Law of Conservation of Matter for example forbids it. this is a scenario. I know this wouldn't happen.

paradox is where impossible exists. ether is growing evidence that time travel is now possible ( in a very small way and not by anything  bigger than a grape)  it seems  only  oen direction it can go.thats  into the future .ergo  such paradox will not exist.

"You invent a time machine".   The solution is right on the first sentence.  A time machine CANNOT be invented.   It will consume an ENORMOUS amount of energy, a megazillion times more than the energy consumed everyday on earth.  If you can build such a big energy generator, then you might have a chance of inventing one.
