He is incorrect. A planet, as he defines it is solace that sustains life, and the sun doesn't. The temperature is too high. His argent is that helium can't convert without life. This is an incorrect statement. The sun, through nuclear fusion turns hydrogen into helium. The sun, through the processes described in the nebular theory is made up of hydrogen and situated in the center of our solar system. Because of its great mass, it has huge gravity. This massive gravity causes high density and thusly high pressure. This high pressure cause the watermelon high temperatures which in turn cause the nuclear fusion. In nuclear fusion four hydrogen atoms fuse into one helium atom, and the two remaining elections become light. But to become neutrons in the helium atom, two of the hydrogens protons must lose their charge which becomes higher energy radiation that our magnetic field deflects. This is what our sun is doing currently, with the waste product of helium. So it's not doing anything with the helium. In the far future, the sun will move off the aim sequence and become a giant star, fusing helium into carbon or another lighter element close to the top of the periodic table. There. Proved wrong through science.
