[Serious] Why defecation?

[BrianSoddingBoru4]

*shrug* I’m neither a biologist nor a biological engineer, so I’m unable to provide you with specifics.

However, there doesn’t seem to be a bar to an omnipotent creator designing organisms able to make full use of the nutrients they ingest with no excretory process (there’s those pesky laws of thermodynamics, but remember - we’re talking about a Being able to whip up an entire universe any way it wants).

It wouldn't hurt to know something of biology and digestion before saying it isn't efficient. From where I stand, your issue appears to be that you simply don't like feces.

No, that’s not it at all. The fact that there’s a waste product at all is an indication that the process isn’t fully efficient (this is what ‘waste’ means). This applies to any system, not just biological ones, that consume fuel and produce waste. A locomotive that uses 100 pounds of coal per mile and belches ten pounds of carbon into the atmosphere is clearly less efficient than an equivalent one that uses 10 pounds per mile and emits one pound of carbon (or whatever the actual figures are - it doesn’t really matter). I can state this is true without knowing how locomotives work.  Similarly, if an animal consumes ten pounds of food and excretes one pound, that animal is not as efficient as it could be. Ideally, all ten pounds of food would go to producing energy. But some of that energy is used for excretion. 

I’m not claiming that digestive systems are NOT efficient. As far as they go, they appear to be sufficiently efficient. I’m pointing out that an omnipotent Creator could have made them perfectly efficient, and that it’s a legitimate question to ask, ‘Why not?’.

In all fairness, you have a point about me not liking feces. In my youth, I shoveled and wheelbarrowed enough of it to float a loan, so I’m not exactly wild about the stuff.
