In the beginning...who cares? Where we came from, where we're going. It doesn't matter. What matters is the here and now. Right this second. How it all began, that ultimate question of the beginning of time, it doesn't matter.
It could have been a god, it could have been the big bang, or it could have been something we haven't even imagined yet. It really doesn't matter. Whether or was 6,000 years ago or 13.5 billion years ago, it was before any of us were born. Being so, it doesn't matter a cent. It's okay not to know.
Come on, just let that rush over you. It is okay not to know. This works for the afterlife too. Whether there is one or not, it's okay not to know. You don't have to say heaven exists. You don't have to assert anything. Just accept that you don't know.
So then, what's the point of life? Have fun. Be excellent to each other.
That's it. Those two sentences encompass life. There isn't anything more to it. Love those around you while they're here. Miss them when they leave.
I know it's a cliché to say this, but life's too short. Most of us have less then a century on this earth, so make the best of it. Don't waste it on uncertainties. God may exist, god may not. It doesn't matter.
Your family and friends do exist. Your life with them is short. Don't waste a second.
