Does helium change into hydrogen in the center of the sun?
No. It is the other way around. Hydrogen nuclei fuses to form helium in the center of the sun.
How can humans change hydrogen to oxygen?
We cannot. Stars can change hydrogen into helium and then helium into oxygen via nuclear fusion, be humans cannot generate and contain the forces necessary to fuse these elements.
