Fackinell, I just don't get this "there must be something more" attitude.
Being alive, on this fabulous planet, here are now, is just amazing, The chances of any one of us actually existing at all are trillions to one. The billions of sperm your dad produced and the hundreds of eggs your mum produced and it was just you and maybe a few siblings resulted.
Even if your mum and dad just made love once, just think about it. 100m sperm and you were the quickest! Not to mention your grandparents, and thousands of generations before, chance meetings, narrow escapes from death. If that arrow had landed just an inch to the left in that battle 1000 yrs ago and killed that young soldier instead of wounding him, you might not be here today!
It's like winning the lotto, but much more unlikely. And you're not happy with that. You want something more???
Imagine meeting someone who had won the lotto euromillions rollover. You go up to them and say "congratulations, what are you going to do with the money?" And they replied "I haven't got time to think about that, I'm too busy worrying about my next euromillions lotto rollover win. After all, there just can't be one lotto win, I mean, what's the point of that?"
I suspect you'd think they were utterly bonkers, and a bit greedy. Be happy with life in the here and now. This is it, one shot. Forget about future lives, heaven, the hereafter and all that rubbish. There isn't one.
Personally, I'm more than happy with my 70/80 years (hopefully). I feel very privileged to have it. And I wouldn't dream of wasting one precious moment of it worrying about the hereafter, or asking some sky pixie for a place in some mythical heaven.
