So where are all the 500 million year old apes? If there's no relationship between the apes' genes, why do they exist at roughly the same time in history?

Because they came into existence from the same or similar mechanism or process. The fact that we have similar genes with a rat does not mean we evolved from a rat. We could have come into existence via a similar process.

OK. What process would create apes, then a couple millions of years later, humans with similar genes?

Nope, it means that we evolved from a common ancestor.
