So much for the hope of the believer. Christ might not decide to return for a day or two. What's that about 10 billion years?

Time is relative to us, who live in time, not to one outside of time. As crawfish pointed out, to a being outside of time billions of years are no different than six days. For St. Augustine six days was too long, so he took the account as figurative, and believed God created everything with one snap of a finger within a second.
A few billion years before God reveals himself to man is meaningless to us also. It is meaningless even to the first man, because the moment God revealed himself to him is the beginning for him. The time before that is only relative to the creator and not to what he created. The creator is outside of time, he feels no long wait, whether it be billions of years, 6 days, or a matter of milliseconds, a being outside of time does not feel time like we do.
It's an interesting thing that you brought up the return of Christ. The disciples were disappointed after Christ death on the cross, because they assumed that he was going to build the Kingdom for them now, for them to wait thousands of years seemed too long. A God that waited for such a length of time did not make sense to them.
Every generation breeds a crop who feels that Christ must return in their lifetime, because a time outside of their lifetime is too long. Man waits, and feels wait, but God does not, he arrives at his appropriate time, even if we feel we have waited too long for his arrival.
