Think about yourself for a minute.
Think about how you got here. On this planet. In this universe.
Think about how, some time ago, your parents got together. And they fucked. Their genes mingled and the results was you.
That sort of stuff has been happening for a long time.
Ever since life first popped up on this little blue dot of ours.
Now think about this for a minute...
Between that first spark of life, that single cell of existence. Between it and you there is an unbroken line of decent, of life.
Millions upon millions of years have passed. Countless generations of all kinds of animals have evolved between then and now, culminating in you.
You carry within you. In your DNA. The traces of all those myriad life forms.
But don't start to think you're special now. You are not the pinnacle of anything. You are not the king of the hill. You're just another step in the road.
