Good questions

Cosmology

How can the sun burn when there is no oxygen in space?

On some days, the sun and moon are visible at the same time, so does this mean the other side of the globe has no moon that night?

Regarding the Big Bang, how can something be created out of nothing?

Evolution

If we evolved from monkeys, why are there still monkeys?

How did all continents “evolve” roughly the same trees?
