Living longer?

It is generally believed by people today that we are living much longer then we use to, as a human race. Often theories such as evolution accompany this way of thinking, that men came from apes and evolved into human-like primates and then became simple humans who lived maybe as much as twenty to thirty years. But does The Bible agree with this theory? And does history agree with this theory? Lets find out: The Bible tells us that the names and ages of the first humans, and although some try to "contextualize" these passages, it is quite plan it is to be taken literally, as one might see upon reading the text. We learn that throughout the 5th millennium BC (5000-4000 BC) and 4th millennium (4000 BC-3000 BC) several men surpassed the age of 800, these include people such as Adam (living to 930 ), Enos (950) and Methuselah (969) and many more. We see that by the 3rd millennium BC (3000 BC-2000 BC) people were living much shorter then they formerly did, for example Abraham lived till age 175 years which is still much longer then people live in our time but compared to just 1500 years previously this is very short. Another example is Abraham's wife Sarah who lived 127 years.

And so we see that such a theory is incorrect, people by The Bible's definition of men use to live longer, even by hundreds of years. The Bible also says in Psalms "The length of our days is seventy years--or eighty, if we have the strength; yet their span is but trouble and sorrow, for they quickly pass, and we fly away." (Psalm 90:10) This psalm is attributed to Moses, who lived in about the 14th century BC. This is the average age people in north America are living today and yet were supposed to believe we are living longer?

So why did people live so long prior to the flood? 

One theory is that prior to the flood water surrounded the Earth as supposedly mentioned in (Genesis 7:11 as "flood gates") 

this theory would explain why people lived for so many years, as the water would prevent the sun's harmful rays from harming early humans skin and plant cells. This is one of many reasons humans lived so long, others include: 

1-Because it was GOD who created Adam, then Eve from a part of Adam, the genes would be pure and perfect and as they had children these genes would remain is much better shape then our corrupt genes we have today.
