the human organs are placed perfectly
The human organs aren't placed perfectly. An omnipotent god wouldn't create many species with the same flaws:
There's a nerve called the
Recurrent laryngeal nerve which is a branch of the vagus nerve. Vagus nerve has multiple branches, two of which go to the heart and two to both sides of the larynx. On both sides of the neck, one of the branches of the recurrent laryngeal nerve go straight to the larynx, but the other branches go through the weirdest loop: they dive into the chest, goes around one of the main arteries in the heart and after that goes back up the neck into the larynx.
pardon me if i've got some terminology wrong, i'm not really well-versed with my human biology vocabulary in English
That's just stupid. If a god decided to create a man, he wouldn't make such a silly, pointless mistake. This same egregiously long nerve is also found in giraffes, whose nerve grows to over four meters long. Evolution, on the other hand, offers a valid explanation of this phenomenon (which, when explained properly takes up a few pages so I do not want to translate/abridge it).
There's a similar thing with male vas deferens:
The vas deferens loops over the ureter, which is another thing a god would have no reason to do (unless he was very inept), but evolution also explains this.
Human eye (and mammal eyes in general) also have things that any designer would spot and change while still in the drawing board. The parts connecting photoreceptor cells to the brain are on the surface of the retina, which means that the light has to pass through them in order to be seen (as the cells are basically pointing to the wrong direction - inside the head). It's not very wise, and it gets worse. Since the nerves are on the retina, when they get together to form the optic nerve to get the signal into the brain, a blind spot is formed.
These all are mistakes in the sense that an intelligent designer wouldn't be very intelligent if he were to design them. Evolution has valid, accepted explanations for all of these - and more, but I don't really feel like typing up all that I can think of. Also, this thread is not for evolution so that's another reason why I'm not bothering to explain it.
Read a book.
ps:it's also the source
