Is there some way to predict or prognosticate the end time for humanities existence on Earth?

If we say a generation is 33 years and one or more native american tribes religously or traditionally spoke of

**7 generations**{**231 years**}as being considerate of our future because of ideas like what we sow is what we shall reap, karma, cause > effect > resultants etc type esoteric high-brama ideas.**231 years from 2020 is the year 2251**, however, what point of time should begin our date with before adding the 231 years of a considerate humanity.

We could start with, some years back, when some believe we crossed over the pars per million { ppm } of greenhouse gases, of which, will make life on Earth for humans not very likely because ofa run-away global warming over a

**relatively short time period 100 - 200 years.**My personal pick of a starting date year is 2010. How I came this startin date is based on the following set of concepts that involve transcendental Pi value i.e. ratio of any circle

**O**to its diameter**--**so following texticonic symbolism**(--) i.e. circle and two radii --, as one diameter value****2231 is my choice date**that humanity will either still be here on Earth of over 1 billion or less than a few million.

.."The latest world population projections indicatethat world population will reach 10 billion persons in the year 2057."

7,794,798,739 billion ---we can round to 8 billion-- is Current approximation of hum an population on Earth.

**7,379,797,139 is the 2015 population**on Earth and if we subtract one value from the other, we get the differrence value of 415,001,600

Here as follows is the process I used tocompare to current and past populations of humans on Earth. How I came to some initial values ex Pi-Time 66.4, I explain at bottom of page.

1} 66.4 { aka Pi-Time } * 3 { 3D } = 199.2 {and I will call mass/energy }

2} 199.2^2 { 2nd powering of mass/energy } = 39,680.64

1} 66.4 { aka Pi-Time } * 3 { 3D } = 199.2 {and I will call mass/energy }

2} 199.2^2 { 2nd powering of mass/energy } = 39,680.64

...note: that, 2nd powering isprocess used in speed-of-electro-magnetic radiation { as mass } calculations....

3} 39,680.64 * 186000 {

__s____peed-of-radiation__} =**7,380,599,040is total energy output**or potential for output, via, Pi-Time { as mass/energy } and that value is very close to numerical value of humans on Earth in 2015 {**7,379,797,139 is the 2015 population }**So 2019, minus 9 years, is the year 2010 and when humanpopulation was approximately equal to cosmic Pi-Time on EMRadiational steroids.

The year 2000 is about 11,000 - 13,000 years sinceGobekli Tepee { First Human religous Temple? } wasbuilt in Turkey.
