2 million years is hardly anything when considering the age of the earth. If you are considering the early earth and its atmosphere you should speak of billions of years.
The inert gases (on earth) are the result of radioactive decay and build up in the atmosphere over time. Argon is (comparatively) rather abundant, Helium and Neon are fairly abundant and have found commercial applications. Xenon, Krypton, and Radon are rare but have been collected and have had an impact on human history. Health nuts use to breath pure Radon and suffer rather gruesome radiation poisoning.

Which gas is least abundant in earth's atmosphere?
After you get rid of the big players like nitrogen (78%), oxygen (21%), and argon (1%) the remaining gases are very rarified. The standard list runs from helium(0.0005%) down to xenon at 0.000008%. There are gases mor are than xenon but they are usually not mentioned.
