It has to do with the words written down in the bible. Either the fowl were created out of the waters, or they were created out of the ground. Which is true? One individual said that both could be true. However, the bible says absolutely nothing of the sort. The arguments that I have heard so far have been ridiculous. It has gotten to the point where the "the book of Genesis has no errors" crowd are making stuff up.
By the way, your "nobody can show it to you, you have to find the truth for yourself" argument is a total cop-out. It tells me that you cannot resolve the problems in Genesis that I have pointed out, and that your failure to do so somehow makes you a more righteous individual. You're better than me because you're wrong? Huh? I'm not buying what you're selling.
The simple explanation is that the Bible testifies inconsistantly.
Gen 1:20-21
20Then God said, "Let the waters teem with swarms of living creatures, and let birds fly above the earth in the open expanse of the heavens."
21God created (AB)the great sea monsters and every living creature that moves, with which the waters swarmed after their kind, and every winged bird after its kind; and God saw that it was good.
Gen 2:19
19(T)Out of the ground the LORD God formed every beast of the field and every bird of the sky, and (U)brought them to the man to see what he would call them; and whatever the man called a living creature, that was its name.
I don't see the contradiction
Secondly, I was not trying to sound or be self righteous to anyone. If I came across that way to anyone I appologize, that was not my intent.
I am an average joe, drive a semi for a living, middle class, high school grad, with some college. (Accounting 101 & 102, Art and Business of Recording, and New Testament Survey @ Moody.)
I have been found guilty of the sins of: blasphemy, greed, adultery, murder, lieing, cheating, obstructing an officer in the line of duty, slander, lust, dishonor to those who deserve honor, drug abuse, alcoholism, and idolatry to name a few. Some of these I have been found guilty in front of an earthly judge.
When I die I will stand trial before the Heavenly Judge. Holy, Righteous, and Just in all decisions, I will have earned the punishment for all my crimes against Him. The prosecuting "attorny" will be standing there, wings spread, seething at the mounth, recalling to the Holy One all of my deeds against this Holy God. He will be seeking the due penalty of banishment from the presence of The Most High and a continous non-consuming burning in the Lake of Fire for all eternity.
It will be at that time that my "Represenative" will speak out on my behalf and say, "Father, this is one for whom My shed blood and broken body has paid the penalty in full".
For insight into what I believe, after the guidance of the Holy Spirit as I mentioned before, you may check out this link. It is a long read but worth it if you want to know how the Spirit has helped me find the truth in His mystery.
May my Lord and Savior Jesus Christ, who died, was buried, and rose from the dead to satisfy the punishment for all of mankind's sins, grant you the grace and peace of the soul He has me.
