You have no idea how much work it took to come up with an explanation of the Genesis events that was on the same level of crazy as Marc and Segovius. I could at least get props for that.
Seriously, Genesis kicks off the human race by stating that the Lord pulled part of Adam out and used it to create Eve. Surely if you can get past that, there's little need for answers to questions like "What did the Anteater eat?" There are a billion ways an all-powerful God, who created everything in the first place, could have pulled this off.
One of the maddening things about Scripture is that sometimes it gives only as much information as one needs to know, and doesn't go into detail into things that distract from the main point the text is trying to convey.
It's almost like the Bible expects the reader to learn to trust God along the way.
