Before we sinned there was no destructive entities our bodies were perfect and we didn't even have need of clothes so attempting to compare the state of everything now to our own concept of what we think good or perfect is will not work.
saying that anything is imperfect as you see it now doesn't reflect on our maker rather it points out how far away from perfection we have devolved since our initial state of perfection and our sin has also affected the world and all created things as well.
In order for anyone to be able to judge any perfect design of anything would require the judge to know perfection otherwise your opinion is relevant only to your own perception.
From someone who so adamantly demands empirical evidence for absolutely everything, I am positively shocked to hear to hear this sort of fanciful tale escape your little typing fingers. Perhaps there's been a mistake...
This much I am certain of we did not create ourselves and random chemical interaction did not create us so all that is left is intelligent design.
Lol, fogive me, but you sound like a caveman.
"Holy crap! What was that!?"
"Oh, round here we call that lightening."
"Wow, where does it come from?"
"Well, none of us do it, that's for sure, and we're pretty positive the woolly mammoths don't do it, although a neighboring tribe swears it shoots out of their tusks, bloody heretics. Anyhow, we figure the most logical explanation is that some dude with a beard who lives in the clouds throws it down when he's angry."
"Huh. Yeah, that's good thinking! I mean, if it's not you or the mammoths, crazy people no one's ever seen before who throw destructive objects out of the sky for no reason MUST be the best explanation!"
why doesnt a cell have odd things that make no sense for form and function?
They do. It's called cancer.
