True, as in an actual doomsday happened?

3200 BC, Solar surges may have been the cause. That was the time the Saraha desert went from habitable to barren desert. That well perserved bronze age man found frozen in 1991 in the alpines, been frozen in 3200BC.

Earth is clearly over populated. Evolution needed a reboot.

The recent data shows that dramatic and potentially deadly effects can result from solar flares and coronal mass ejections. Substantial data suggests that an event, similar to the one anticipated in the 2012 "doomsday" scenario, occurred about 14,950 years ago and was recorded by ancient humans. This event appears to have lasted for several years in duration and was responsible for the abrupt end of the last ice age as well as a substantial culling of the human population.

The surprising findings of LaViolette, supported by other research, suggests that the extreme solar event corresponded to powerful radiation coming from the center of the Milky Way Galaxy and was associated with gamma rays and cosmic dust. Recent observations have shown a dramatic increase in gamma ray energy in the Glaxy's equator which will be in maximum alignment with our solar system on December 12, 2012. The past records in ice cores (strata from 13,880 to 13,785 BCE) suggest that intense radiation from this last event could have lasted many years. It seems highly likely that this alignment will cause another extreme solar event since other factors precipitating a "solar maximum" (i.e. the opposition of major planetary barycenters) also converge on this exact date.

The fact that galactic centers routinely radiate lethal gamma rays makes it unlikely that life, at least as we understand it, can survive in the universe. Sooner or later it is destined to be zapped.

A new genetic study of Y-chromosome variation by Dr. Marcus Feldman of Stanford University shows that the population from which the world's present population is derived consisted of about 2,000 individuals. Somehow, humans, flora and fauna did survive the past doomsday and some may yet survive past 2012. Indeed, many of the ancient prophecies I have encountered in my travels around the world have spoken of a "bright light" or "flash" followed by the "good seed" (i.e. humanity) which would rise up and repopulate the world.[7]

Organisms on Earth, including humans, have evolved during quiet times -- between the lethal blasts from our own Milky Way center. This means that we are indeed quite unique (and lucky). But it also means that our ultimate demise is part of the natural order. This universe is larger than ourselves and our lives. We are just transient phenomena, seemingly running counter to the laws of entropy, yet a part of the cosmic reality. This is neither good or bad. It simply is

tl;dr

I completely agree.  Except for the fact that there will be another predicted Doomsday after that.  It never ends.

Did the mayans mange to predict their own extinction?

Not gonna happen.

When the older Mayan calendar was coming to an end the Mayan's added the long count to gain thousands of years.

I'm sure if they were a civilization now they would do the same thing.

Sure there may be some strong solar activity in 2010-14 but, it will only affect some electronics like it did in 2001.

I tend to agree with this. The OP's pseudo-science relies on the fact that astrophysicists have not entirely worked out how gravity works over long distances in space, nor proven the existence of gravity waves.  I guess what I'm saying is the OP is possible, just not very likely.

agreed.

Michel de Nostredame followers are trying to connect everything together now with the Mayan calendar this time around, they had it worked out with Hillies comet, then it was May 1999 when all these conjunctions was going to take place now its the Mayan calendar.
