I plan on dealing with several issues raised here. I will continue to edit this post, and will answer questions only after it is completed.
For reference purposed here is the modern populations of several mid-east and countries near the mid-east.
Israel 6.5 million (10 million counting occupied territories)
(note: most of modern Israel's population is compacted in a relaitively small area of this small country) http://www.us-israel.org/jsource/History/ispopmap.html (also note that ancient Isreal was approx 3 times as large as modern Israel during the times of Solomon)
Jordan 5 million
Syria 16.3 million
(note much of Jordan and Syria were parts of Israel in the time of Solomon)
Egypt 66 million
Ethiopia 61.1 million
Sudan 29 million
Modern Growth Rates of the Two Least Devolped Nations from Above
Ethiopia 3.29%growth rate
Sudan 2.31% growth rate
Ancient Populations (as recorded in the Bible)
Numbers 1:46 census 603,550 males above the age of 20 who were able to go to war
Numbers 26:51 census total 601,730 males above the age of 20 who were able to go to war
(note: this is not referring to a full time standing army, but only the number of available males.)
The total population of Israel based on these figures would have been approx. 3 million.
2 Chronicles 21: 5 census 1,570,000 males who were able to go to war
Are these censuses credible? (under construction)
Math Supporting Biblical Numbers
How Big was Israels Army?
The number of men of military age given in Numbers (603,550) is not the number of the fulltime standing army, but the number of males who were able to go to war. I am not in the army, yet I am able to go to war. It is incorrect for people to make calculations claiming that these were "armed men" or a standing army.
The number of men of military ability in the census in 2 chronicles 21:5 was also not the size of the standing army, but as in Numbers the size of the population of men who were able to draw sword. This is shown by the fact that a census had to be taken. Military units are divided into divisions of pre-set numbers so there is no need to take a census of them!
1 Chronicles Chapter 27 gives the size of the standing army of Israel at 288,000 of which only 24,000 (1 division) was on duty at any given month.
Too few chariots to be afraid of?
"And he took six hundred chosen chariots, and all the chariots of Egypt, and captains over every one of them." Exodus 14:7 KJV
" and he took six hundred select chariots, and all the other chariots of Egypt with officers over all of them." Exodus 14:7 NASB
Too much poop?
The tribes of Israel were not one large homogenous camp, but were actually several relatively independant camps arranged by tribes in to a rectangular pattern. There were 3 tribes on each side with a large open space in the middle. Though each of the 3 tribes on each side were combined into a single large camp, they were still distinctive. Numbers chapter 2 gives the arrangement.
Also each tribe was sub-divided.
Thus for someone to go to the bathroom outside the camp did not require a long walk but only to go to the local "poop" station. Each tribe probably had dozens of these locations. The argument above assumes a single poop station for the entire 2-3 million people camp which is ridiculous. The argument also places everyone into one large camp which is incorrect.
Furthermore the argument assumes that they stayed in place for a whole month which may not be valid.
Also the one square foot per "incident" factor would be invalidated by the possible use of trenches at these locations.
Furthermore a calculation was made of how many people were squatting at any given time. This same argument could be applied to any realatively large city today such as Oklahoma City, Oklahoma. The fact that thousands of people are "squatting" at any given time does not disprove the existence of the numbers of people in Isreal any more than ot disproves the number of people in Oklahoma City today.
Finally even if there were a poop problem (which I don't believe there was) this does not disprove the existance of the numbers in the exodus. If the population of Oklahoma City were to go into the Oklahaoma plains they may have a poop problem, however they would still exist.
