I'm not following here. To me, neither story does much to inform the discussion about old earth/young earth.
1) the sealed cave ecosystem -- totally cool! I love the variety of life that the Lord has made. I'm a bit saddened by one comment -- that they may have seriously damaged the ecosystem by introducing different air (oxygen) when they went in.
In any case, I don't see what this has to do with old earth/young earth. There are many articles about the flaws in any dating mechanism, so without more detail its hard to discuss the reported "age" of the finding. In fact, I think a powerful argument could be made that this finding actually supports the young earth / global flood view. Consider a pocket cave (YEC would say created by the flood) filled with animals that can create a symbiotic ecosystem. Is it more reasonable to believe that cave existed like this for a few thousand years or for millions of years?
2) The meteor could very well have been how the Lord punctured the water canopy of the earth and set off the global flood, as well as causing tectonic stress that opened the water from under the surface, etc. No problem here. Again, ages are dependent on the dating systems, and would require a lot more data to even start to discuss intelligently. One point of YECs like me is that there are known BIG problems with the various age determination techniques -- something commonly glossed over by the media and many scientists.

The water canopy NEVER existed - there's several pages documenting why it's an impossiblility - below is just a quote from part of that page, which refutes YEC AND the global flood.

Air can hold, at most, 55 grams of water per cubic meter. In contrast, liquid water is at a density of 1,000,000 grams per cubic meter. The ratio of the two numbers is 1:18,000. Therefore, a flood of 1 mile thickness (which would cover only 1/5 of Mount Everest), would require 18,000 miles of canopy. Besides the problem of gravity (which would bring the whole thing down), such a thick layer of water would completely block any light from the Sun from reaching the earth.
(The stars were visible on earth from day 4 - if you hold to a literal 6 day 24-hour period, but I still believe that the overwhelming majority of scientific findings confirms that the earth is older than 6,000 years. Besides that, I majored in history in college, and the YEC timeline doesn't hold up at all to the historical record. Especially not with skeletal finds such as Kennewick Man in Washington state which dates back to 9400 years.)
Even a canopy of only 40 feet of liquid water would double the earth's atmospheric pressure, which would kill many animals, including humans. This pressure would also increase the temperature on the earth to a scorching 220°F. Most animals and plants do not survive long at this temperature.
Another problem is getting the water out of the atmosphere and onto the ground without cooking everything on the earth. Each gram of water vapor that condenses to a liquid releases 539 calories of heat. For a global water layer of only 40 feet deep, 6.22 x 1021 grams of water would release 3.35 x 1024 calories, raising the temperature of the earth to 810°F. Such a scenario would definitely kill all life on earth, but would produce a tremendous air conditioning problem for Noah. And a 40 feet deep flood would certainly not be global.
Here's something else from Wikipedia
PHYSICS OF THE VAPOR CANOPY
In order for the vapor canopy to explain a truly global flood covering the highest mountains (as apparently described in Genesis), the atmosphere would have had to have a composition of about 900 parts water vapor to one part of what we call air today. To prevent this from condensing, the temperature would have to be raised to the point where the partial pressure of water equals 900 atmospheres. This is equivalent to the surface of the planet having the same environment as a 13,000 psi boiler, completely inhospitable to any form of life.
Some creationists respond that the "vapor canopy" was composed not of vapor within the atmosphere, but of ice crystals
above the atmosphere. (Morris's original proposal relied on water vapor, not ice.) Such a spherical shell of ice orbiting the earth above the atmosphere would not be physically stable.
Additionally, the fall of so great a quantity of ice (or of anything else) from so great a distance to the earth's surface would produce an enormous amount of heat converted from the gravitational potential energy of the ice. The consequence would have been not a flood but a poaching by superheated steam.
Basically, you'd be talking the same effect as Venus, and that canopy would have made life impossible.
Not even answersingenesis.org accepts the vapor canopy theory -

In addition, there's more than one crater on the face of the earth - the most famous one that comes to mind is Meteor Crater in Arizona, but there are others scattered over the globe. Also, when in the 6 days was the moon, mercury, the earth, and other planetary bodies bombarded by meteors, the evidence of which is still plainly visable, especially in the case of Mercury and our Moon?
