I agree with that. I wouldn’t mind never getting old, either.
In fact, that’s (part of) the promise:
“Let his flesh become fresher than in youth.” — Job 33:25
Job 33:25 - Elihu Rebukes Job
With the way our bodies rejuvenate themselves, it’s easy to understand how we could live forever.
It’s harder to explain why, as humans age, the process breaks down.
But imperfection is an inherited condition. — Romans 5:12
Genesis 3 shows that the issue of Jehovah God’s sovereignty (right to rule) was raised, and Adam gave it validity by him choosing to rebel.
Time was / has been required to settle that issue…. Humans have pretty much failed at all forms of rulership, establishing a record of ineptitude & incompetence. For all to see.
Humans have not failed in leadership. The reason there is now 8 billion of us is because most people, most of the time, work together.
8 billion doesn't happen due to failure. Nothing perfect, but the secular world has produced 8 billion. I expect the secular world will also produce interplanetary travel, colonization, and immortality soon as well.
