If you believe that the world and the people in it are products of Intelligent Design, then your Designer did a pretty shitty job.
I’ve got three crushed discs in my back, since the spine was not “designed” to be operated in a vertical position. Likewise, my knees and hips are wore down to bone-on-bone because they were not “designed” to support the entire wieght of my body. And who would “design” a creature with an endoskeleton, and then allow something like arthritis to exist? That’s like Chevy including free rust on every new car.
Why would you “design” teeth to fall out? Or cataracts? Or even toenail fungus?
If a first-year engineering student turned in a design as flawed as a human being, they would not only fail the course, they would probably be asked to leave the school, for being too stupid to ever complete the course.
I find it easier to accept the possibility of travelers from another planet, (or dimension, the future, etc.) than the idea of a supposed omnipotent being, who has the power to create the world and everything in it, but still did such a poor job of it.
