Moody Adams - book Proof When someone tells you they do not believe in miracles, tell them to try closing their eyes on a black, dark night and see how many flying insects they can catch. Then you might tell them that the little Mexican free-tailed bats of Texas catch and eat an estimated 20,000 tons of insects per year. They do this without eyes, in a world of total darkness!
While their larger brothers feed on fruit, small bats feast on insects. The little blind creatures catch them by means of sonar—sending out sounds and listening for echoes bouncing back.
Their sonar requires vocal cords that are marvelously designed. They are capable of sending sounds that reach amazing frequencies as high as 80,000 hertz.
Bat sonar also requires fabulous ears. They are capable of picking up faint sounds even when there are loud dogs barking around them. The Whisper bats got their names by emitting very low sounds, or mere whispers, which their sophisticated ears can still pick up.
After these sounds hit objects and echo back, they are relayed to the bat’s brain. Then the brain analyzes the echo and determines the size and type of object the sound bounced off of. Their brains are able to analyze the sounds and tell the difference between an insect and a brick wall.
All this is done while the bats are flying at tremendous speeds—often with the little insects also moving rapidly.
Bat sonar becomes even more amazing when you consider they operate without ever shutting down for repairs. If their sonar failed they couldn’t get food and would die.
It has taken the greatest scientific minds thousands of years to develop sonar. The bats are born with it installed. How could this have happened without an intelligent Installer?
