We as human beings have come to believe many things as fact.
Truth is, most are just illusions...
Time doesn't exist, we only have a perpetually moving expansion and/or contraction of the universe
If you ever want to really discover how real something is, try holding onto it...it will eventually disappear into the vastness it came from.
everything that you see, or have ever seen, will eventually biodegrade back into the earth, or universe...Nothing is made to last forever.
The human ego will/does argue it's importance to death, and it is it's biological imperative to self preserve, but reality is reality.
We are here for a reason...What reason? You decide, but I implore you to never get so set into your own importance that you fail to see the ultimate purpose.
What is the purpose? That's what you're here to discover!
