Intelligent Design, Proof V

If that is so, why don't you make another species (donkeys for example) return to their birth places from anywhere in the world
Then we will not need GPS we can use Donkeys!

Red herring; my ability or inability to alter the behaviors of an existing creature has no bearing on whether or not that behavior could arise via evolution. Moreover, the creature in question would need a dedicated navigational apparatus, like the eel's magnetite compass, to be able to do so.

What you just said was either dishonest, or breathtakingly stupid.

They must be in millions and outnumber any others?

Not outnumber, no. But a few eels spread about the vast population of eels wouldn't be enough for that trait to become embedded enough. It would need to be shown to have a consistent advantage, or at least a less than fatal detriment, to persist, and since the trait we're talking about is "breeding anywhere else but the point at which you spawned" it's too random an outcome.

This supports the existence of intelligence guidance.

No, it supports the existence of a magnetic field around the planet, and the eel's ability to utilize it in navigation.

What was it I said about unevidenced assertions being dismissed out of hand? Yeah, that. Do you have any evidence, or shall we expect the same petulant insistence we've all come to know and be nauseated by?
