Mass of the sun: 2 x 10^30 kg Mass of a hydrogen atom: 1.67 x 10^-27 kg So there are 1.2 x 10^57 atoms in the sun. And we need the sun. The mismatch is caused by someone extrapolating an exponential trend in one area well into the future, ignoring physical reality. Anyone with a good grasp of high-school physics should have noticed this before the slides were released.
