The other big problem with teaching ID has had a thread here before: what would the lesson plan be? Maybe:
​
Tuesday. First 30 seconds of class: "Some people posit that some intelligent force did something like designing the universe or life at some time in the past. These people don't know who or when, or what this Designer did. So let's move on to the Krebs Cycle."

Dammit, Chiroptera, I wish I still had some of that youthful fire you show in posts like this! Don't let it get away from you.....

Re: The origins of free Oxygen
but how do we know there was no O2 in the air before that? I was taught that there wasn't in school, but how can we know?
​
We can know by looking at the minerals that are in rocks more than 2.4 billion years old. There are multiple chemical species that show that oxygen was absent in the atmosphere back then - like iron sulfides where you would have iron oxides now, uranium minerals in river-laid sands that would oxidize to different minerals if free oxygen had been around, molybdenum minerals that would never have fallen out of seawater solution if it were oxygenated like today.
​
Plenty of evidence. Wikipedia can lead you to some of the high points:

Re: Wow
How do you know what it was like. were you there?
​
Please don't say that. You "weren't there" before 1900 yourself, I'm quite sure, and saying that reminds one of Kent Hovind.
​
Oh, and a big HOWDY, and excuse my bad manners in not saying that first. I'm only to my third cup of coffee.
