Yea, make our own planet. Simple! This got modded 5 Insightful?

Seriously, I can't think of anyone else who believe that humans will create planets. No, this is not flamebait or trolling - it really is the only ones I can think of that might see this as a possibility, although not while still human.
And if there really are someone delusional enough here to think that we could create our own planet while being mortal humans, you really need to think about the scale here. It's not just huge, it's immense. We only scratch the surface of this planet.
If we found Mount Everest sized rocks (~3x10^15 kg) in a solar system, we would need around 2 000 000 000, that is 2 milliard (or billion for those who use the short system) of them to create a planet with Earth's mass (~6x10^24 kg). Imagine the power and time needed to move one Mount Everest. Each Chomalungma sized rock is about 28 milliard (or billion in the short sytem) times the weight of the space shuttle.
And we're not just talking scale here. Think about how you would adjust the orbital speed of the mass you assemble so it would stay in orbit as you add to it. Or how to cool it down from all that kinetic energy -- how long did it take Earth to cool down? Or how to survive the flares of Barnard's Star?
Niven and Lucas make great space operas. But we have to admit to some limitations. Come back in a few million years, and whatever species have descended from us may have a different opinion. But us? No, we have no chance.
