dead air?

So.....I'm watching "Tutenkhamun," a movie from a few years ago, about the discovery of the tomb of that ancient pharaoh.

They find the sealed entry into the tomb, the guy knocks a hole into the wall, and inserts a lit candle tied to a stick, so as to see what's inside.

And then later they make an opening into the tomb enabling three of them to crawl through and walk around.

I never paid much attention to science, having found it boring--humans are much more fascinating than anything "scientific"--but if I recall the lessons correctly, at some point I learned that when a space was closed up for years and decades and centuries and eons, the oxygen inside it evaporated, or whatever oxygen does.

Leaving dead oxygenless air--pretty much useless to breathe, much less for keeping an oxygen-burning flame on a candle lit.

And so when coming upon long-sealed-up areas, the place was left alone until there'd been enough time for the movement of air in and out of it, bringing with it oxygen. Depending upon how the new "ventilation" was, sometimes this would take days and days before some place was safe for entry.

Did I misunderstand something?

1. More concerning to me is what airborne pathogens had been sealed up in that tomb which these so-

called scientists just opened up and released into our current atmosphere. Very strict containment protocols were used when bringing samples back from the Moon...why wouldn't the same be followed for opening up containers/rooms/etc that have been sealed up for thousands of years??

2. I do not think the space was "oxygenless"

It was most likely very stale, musty and possibly even spore or bacteria laced air. Whatever it was not air we should breathe. Pores in rocks and microscopic holes would allow small but insufficient air movement.

They vented to "freshen the air" and make the air fit to breathe.

3. We take far more precautions today when opening tombs than we did in 1922. ...

Well at least we wear masks and gloves.

Mysterious black granite sarcophagus is finally OPENED: Mummified corpses of ancient Egyptian soldiers with cracked skulls are found bathed in sewage
The 6.5ft (two metre) high coffin was first discovered earlier this month and unearthed in recent days
The 30-ton (27,000 kg) tomb was found buried 16ft (five metres) beneath the ground of the city
The coffin was also filled with sewage water, which is believed to have increased the rate of decomposition
The three mummies will now be moved to Egypt's Alexandria National Museum
