My mud and their dust

It is from my dirt and my water, my mud,
that is the mix from which they are made.
It is upon my facade that they reside
and then to dust degrade.

If they rose from within me,
or fell down upon me,
God and his Science will recall.

But I, without a care or concern,
let their history be told
simply by deduction,
for their destruction
it is evident and their legacy sown
their loss utterly
and completely,
their own.
