Adam and Eve are not comparable. They were directly created by God who, as you stated according to the account, Who breathed life into them. They were not conceived and did not go through gestation in the womb as babies have done since.
Your commentary on the Numbers passage is full of speculation and your own assumptions. A husband could have been suspicious that their spouse was involved in adultery for a variety of reasons. It does not necessarily have to be that the woman is pregnant. For one thing, the test would also demonstrate if a woman was NOT pregnant, therefore innocent of the charge of adultery by her suspicious, slandering husband.
Please, never use the word "assumptions" in a debate unless you can back it up. And I did not say that he could not be suspicious. I said the one sure way that he could know. This was a very serious test and was not to be done on mere suspicion. Plus you ignored my warning. I told you that you need to consider it in the context of what happens during the test. You did not. Your "assumptions" claim has been refuted.
And we are not concerned with the times that the woman was not pregnant. That may have been the case sometimes. Now it appears that you did not even read it
Verse 22:
May this water that brings a curse enter your body so that your abdomen swells or your
womb miscarries.”
Bolding mine.
verse 27:
If she has made herself impure and been unfaithful to her husband, this will be the result: When she is made to drink the water that brings a curse and causes bitter suffering, it will enter her, her abdomen will swell and her womb will miscarry, and she will become a curse.
That is twice that it says that she will miscarry if she has cheated. A pregnant wife that should not be pregnant would be a pretty clear sign of cheating even if no one saw.
