Fluther challenge: use "Observational" Science to show that Intelligent Design and Young Earth are false.
In the latest debate, Ken Ham talked about Observational Science and Young Earth. They do not accept “Historical” science, since no one was there to observe if it really happened.
How can we use Observational Science to prove the opposite?
I’ll start: we can use “Observational” geometry to figure out that most stars are >35 quadrillion miles away. We can measure the speed of light (186,000 miles/sec), and divide to figure out that most stars are >6000 light years away. So star light reaching us started >6000 years ago => therefore the Universe is >6000 years old. Earth was created at the same time as the Universe, as I understand Genesis, so is >6000 years old too.
