Just asking (16): where did the poo come from?

I used to do morning jogs along Shatin Shing Mun River.

People were walking dogs.
Old folks.
Maids.
Mainly.

Not often but every now and then poo was right on where it shouldn’t.
It’s annoying.
Hazardous too.

I kept jogging but mental computations began.

A. An irresponsible dog owner didn’t pick up despite being aware of it.
B. Or just too occupied with cellphone and chat, not to the dog.
C. Or maybe a stray dog.
D. Or a lousy maid.

C was rare in Shatin.
D was clearly tainted by stereotypes and racial discrimination. Should try not to entertain.
A was the most likely, and B is a variant that was charitable.

By the time I was far away from the poo and almost done with the jog, I had already let go.

But never had I let E or F scenarios come into my mental calculation:
E. Someone placed the dog poo there.
F. The poo got there by inexplicable random accident.

I’m no Einstein.
Just an average bloke.

So simplicity is beauty.
E and F are too concocted.
Too elaborate and too taxing for an average mind.

Clearly there must have been a dog.
Logically there also must have been an absentminded owner who walked it.
That’s already a kind and no-discrimination mind at work.

Simple.
Straight forward.

For since the creation of the world his invisible attributes—his eternal power and divine nature—have been clearly seen, because they are understood through what has been made. So people are without excuse (Rom 1:20, NLT) .

Just asking.
Why go complex and concocted?
