The big bang or God created it. Mostly the big bang is the scientific reason and God is the religious reason.
2012 was predicted by the Mayans because they did a very long calendar and for some reason decided to stop at the year 2012 so people think that it is the end of the world or something bad is going to happen
all of thesesanitation, nutrition, and medicineThe primary reason is clean drinking water. This can be considered part of public sanitation. Clean drinking water and universal public sanitation are responsible for about 80% of all increased life expectancy during the 20th century.
i think the best reason is: if we earn more so we can spend a luxurious lifestyle
The main driver of life expectancy rates is infant mortality rates have fallen. Although vaccines and treatments have had some real effect on it as well, the fact that babies survive at ever increasing rates takes most of the credit.

A dolphin is a mamal and has a life expectancy of approximately 3-4 weeks. Dolphins grow VERY fast which is the main reason the are farmed food food by the chinese.
Left-handers don't have a short life expectancy compared to right-handers, no.However, what has been discovered is that on average, right-handed people live three years longer than left-handed people. The reason for this is unknown.
Since the emergence of human civilization (generally, with the advent of writing), average human life expectancy has hovered in the high 20s-30 year range. In civilizations with high levels of sanitation (or, in nomadic societies where it was less of a concern), life expectancy was a bit over 30.So, for typical societies in Old Testament time periods, 28 would be reasonable. For New Testament societies, a bit older (perhaps 30 or so) would be reasonable.One reason life expectancy was so low is that infant mortality was very high. If one discounts deaths in infants (i.e. death before the 1st birthday) from life expectancy calculations, increase the above numbers by as much as 10 years.
It can be down to a numorous amount of differences such as climate, poverty, road congestion, crime, availabiltiy of decent health care and many, many other reasons. For example, in countries where there is a much higher national crime level, the life expectancy will varie. A rich country does not nessecarily have a long life expectancy due to people in rich countries generally being more unhealthy and having a higher death rate due to high fat content and smoking related illnesses
