But to your question, "Why on earth do you need to experiment to test for something that is so patently obvious..."
Let's us the two examples of genius you've already provided. By your logic, gravity doesn't warrant investigation - after all, what goes up, must come down.
Why do things fall?
Because of gravity, of course.
What's gravity?
The thing that makes things fall, dummy.
Talk about begging the question. Newton and Einstein both studied the concept of gravity and its consequences, and what they learned (and taught the rest of us), is that what is "patently obvious to the casual observer" means nothing. There is no "up".
Do you consider that nothing can be verified as accurate and true unless it can be reduced to a scientific experiment?
Why on earth do you need to experiment to test for something that is so patently obvious to the casual observer and even Dawkins admits that the universe and life give the appearance (illusion) of design?
And by the way, I would love to read the conclusion you say Einstein reached.
“I do not believe in a personal God and I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it.”
Albert Einstein
I never said anything about Einstein believing in a personal God. Stop putting words in my mouth and misrepresenting what I said.
My question was merely .....So, Newton and Einstein were wrong when they concluded that the universe must have had a designer based on their observations?
