If you knew nothing of time, and you knew nothing of how time works. Then you would not know what time to sleep and wake.
If you knew nothing of time and you wanted to book a holiday, you would never be able to go to your destination as you would never know what date it would be and what time you coach leaves.
If you knew something of time, you would be escalating the vacuum of space.
It would then become apparent that the time you spend with your family and friends will become precious as you would never know what came or had gone before.
But why would time disappear, as you know time goes forwards and not backwards. As it starts to unwind from the broken promises of kingship.
When I say Kingship I mean a time that had no time at all, and those that were alive had unlimited time to live. An Eternal for that matter.
But we never needed knowledge only freedom to live.
