I'd just like to point out as well, many of the early scientists were in fact religious, at least to some degree. Science does not have roots in trying to disprove the bible, or deliberately trying to weave some false picture of the universe to intentionally contradict the Bible. It just happens that way because the bible is not scientifically accurate. Science is seeking to establish in a methodical way "what DO we know?" When science is working, all the pieces fit together well, and when something is out of whack, the pieces don't fit together well (which is why research into gravity, dark energy, and dark matter continue as we speak).
If our scientific understanding of how old the earth, various fossil specimens, and how life has changed through time on this planet were off by the orders of magnitude suggested by 'young earth' creationism... nothing would fit into place at all. Sitting through a biology lecture would be so riddled with flaws and contradictions every student (many of whom are religious) would be scratching their head and vowing to set the record straight.
As the Talk.Origins response hints at... ice samples are collected from many locations around the world, and after painstaking research and comparisons, they have been used to reconstruct a timeline of global atmospheric conditions. I'll bet you anything that the atmospheric conditions suggested by the ice samples taken from around the aircraft (oxygen and co2 levels) are measurably different from samples taken at similar depth further inland.
This is the difference between real science, and just taking everything at face value.
