Sorry, but that 747 analogy is just ridiculous.
Even if we were to use it as a highly flawed analogy for evolution, we'd first notice that 747's didn't start out as 747's, they didn't even start out at Kitty Hawk, NC in 1903.
In a larger sense they started with birds hundreds of millions of years ago learning to fly and with pre-humans hundreds of thousands of years ago learning to make tools.
They started with balloon flights in the 1700s and with 1800s' engines producing mechanical power, etc., etc.
Of course in theory evolution proceeds without conscious direction and without leaps in imagination.
On the other hand, the human directed advances in 100 years of aviation (Wright bros to today) took evolution hundreds of millions to eventually produce, say, the Peregrine falcon.
Sure, I "get" a lot of people say God did it all in a few thousand years, and certainly He could have.
But for some reason the physical evidence He left us suggests much longer periods.
Given the football stadium analogy do you have a guess as to how big an average amoeba would be compared to that stadium sized bacterium?
