the artist is Yuurikin and the character is a OC of Arynbun named Reno. it was posted before 2020, i know because thats when i found the cropped version. i asked the artist himself for it but they deleted it from their files, i asked the person that commisioned it but they dont want to give it out for some reason. stuck to searching.

Our whole universe was in a hot, dense state
Then nearly fourteen billion years ago expansion started, wait
The earth began to cool, the autotrophs began to drool
Neanderthals developed tools
We built a wall (we built the pyramids)
Math, science, history, unraveling the mysteries
That all started with the big bang (bang)
Since the dawn of man is really not that long
As every galaxy was formed in less time than it takes to sing this song
A fraction of a second and the elements were made
The bipeds stood up straight, the dinosaurs all met their fate
They tried to leap but they were late
And they all died (they froze their asses off)
The oceans and Pangea, see ya wouldn't wanna be ya
Set in motion by the same big bang
It all started with the big bang
It's expanding ever outward but one day
It will pause and start to go the other way
Collapsing ever inward, we won't be here, it won't be heard
Our best and brightest figure that it'll make an even bigger bang
Australopithecus would really have been sick of us
Debating how we're here, they're catching deer (we're catching viruses)
Religion or astronomy (Descartes or Deuteronomy)
It all started with the big bang
Music and mythology, Einstein and astrology
It all started with the big bang
It all started with the big bang
