I just mentioned this in another random comment so I thought I'd mention it on the off chance someone else is as boring as me.
A WT publication once talked about a bird I will never forget... The Arctic Swift. It travels further than any other bird and migrates across the world. With no gps or map how can any animal do this unless god designed the bird with instinctual earthly knowledge?
I must admit, this was once good enough for me. Not so much now... And there is a simple answer thatI could have gone and read about... Face palm.
Birds have compasses in their beaks, so yes they do have gps.... They have the mineral magnetite in their beak which allows them to co-ordinate their travel around the earth via the magnetic fields.
It really is that simple... I believe I once read that humans too have magnetite in their nose..... Maybe just female noses....
