Sea Breeze: Keep in mind that materialism is an ideology that competes with God
This is what Lewontin was referring to. The theist presupposes god, then demands that science put this presupposition on the same level as the things that science is able to observe and test. You have it backwards: God is an invention designed to compete with scientific discovery and advancement.
YECs are constantly making claims about science that they clearly don't know enough about (or are deliberately lying about, for the small handful who understand the science). The researchers you quote are willing to admit that their theories may need to be changed. They still need to study these images and make sure they understand what they are seeing, precisely because they do not have presuppositions to defend.
And, again, this would affect their theories on galaxy formation, not on the age of the universe.
Sea Breeze: For everyone else with a free and clear mind, these images look JUST LIKE human footprints.
No, really. They look like cartoon footprints. Compare them to actual human footprints and the difference is so stark you'll wonder how anyone could fall for it. YECs fall for it because they want for it to be true. If they treated these finds the way scientists do, they'd recognize them as either fake or misidentified. I guess you can describe them as "chained to an ideology."
