To quote Tim Minchin:

Isn't this enough?
Just this world?
Just this
Beautiful, complex, wonderfully unfathomable, natural world?
How does it so fail to hold our attention that we have to diminish it with the invention of
Cheap, man-made myths and monsters?
If you're so into your Shakespeare
Lend me your ear
"To gild refined gold
To paint the lily
To throw perfume on the violet
Is just fucking silly"
Or something like that
Or what about Satchmo?!
"I see trees of Green
Red roses too"
And fine, if you wish to glorify Krishna and Vishnu in a post-colonial, condescending bottled-up and labeled kind of way then whatever, that's ok
But here's what gives me a hard-on
I am a tiny
Insignificant, ignorant bit of carbon
I have one life
And it is short and unimportant
But thanks to recent scientific advances
I get to live twice as long as my great great great great uncleses and auntses
Twice as long
To live this life of mine
Twice as long to love this wife of mine
Twice as many years of friends and wine
Of sharing curries and getting shitty at good-looking hippies with fairies on their spines and butterflies on their titties

I know it's about superstition, new-age nonsense and "spirituality", not other planets. But it's just so on point to me for everything where we fail to appreciate this wonderful world around us.
