Thing called me

There's a thing called me
I'm inside you, I won't go away
As a matter of fact
I will stay
I've been here
Six million years
And more that I cannot recall
I've been through you
And though me
I'm everywhere
What's down today
Here I am
I'm standing... here
In a corner of your existence
Navigate back to the spot
Because they are all young
And they know nothing
They don't see
They mainly smell
And the click of a trigger
Would make them smile
(dual? tool?)
As of the universe
Don't come near me
I'm a human being
Home to a soul
The six million I said
Doesn't go back to the energy
Direct energy
