However brief our time in the sun, if we waste a second of it, or complain that it is dull or barren or (like a child) boring, couldn't this be seen as a callous insult to those unborn trillions who will never even be offered life in the first place?

Cheetah genes cooperate with cheetah genes but not with camel genes, and vice versa. This is not because cheetah genes, even in the most poetic sense, see any virtue in the preservation of the cheetah species. They are not working to save the cheetah from extinction like some molecular World Wildlife Fund.

Be thankful that you have a life, and forsake your vain and presumptuous desire for a second one.

The Universe does not owe us meaning.

One of the possible reasons why we might be good is that we're frightened, frightened of God. We want the reward in Heaven, we don't want to go to Hell. That would be an ignoble, ignominious reason for being good, and I think that if anybody was good to you just because they hoped for a heavenly reward, you wouldn't respect them, you'd probably give them a wide berth.

What is interesting about the scientific world view is that it is true, inspiring, remarkable and that it unites a whole lot of phenomena under a single heading.

Religion has been a powerful weapon in the hands of governments, in the hands of priests, in the hands of kings who have used it as a weapon to keep down the populace. It is a wonderful way of disciplining people and making them do what you want, to tell them that if they don't do what you want they will, for example, go to Hell.
