I seriously doubt ether A&E knew what god was talking about when he mentioned pregnancy, what giving birth was, or what children were
Disagree strongly with this statement. When God instructed Adam, before Eve was created, to begin the studying of all the animals and naming them, he put Adam to work that probably lasted years and year.
Gen 2:19 And out of the ground Jehovah Elohim had formed every animal of the field and all fowl of the heavens, and brought them to Man, to see what he would call them; and whatever Man called each living soul, that was its name. 20 And Man gave names to all cattle, and to the fowl of the heavens, and to every beast of the field; but as for Adam, he found no helpmate, his like.
It is my opinion that Adam was alone for at least 40 to 50 years doing this work, and simply existing - before God created his wife, Eve. This is why I think Adam sinned. He had been alone for so long that once he was given a companion he loved, he could not again face loneliness. While this displayed a lack of faith; it also makes him very human.
Offspring
Because of being familiar with the animals, having lived with each kind so as to give them names, he most certainly was acquainted with them bearing offspring, with them engaging in sex, with them raising their offspring.
God wants us to enjoy sex with our mates
Proverbs 5:15 Drink waters out of thine own cistern, and running waters out of thine own well. 16 Thy fountains shall be poured forth, as water-brooks in the broadways. 17 Let them be only thine own, and not strangers' with thee. 18 Let thy fountain be blessed; and have joy of the wife of thy youth.
19: As a lovely hind and a graceful roe, let her breasts satisfy thee at all times: be thou ravished continually with her love.
Christian times - what's up
Here I would encourage you to read 1 Cor ch. 7 several times to get the gist of it, but let me briefly show what is up.
1 Corinthians 7:28 But if thou shouldest also marry, thou hast not sinned; and if the virgin marry, they have not sinned: but such shall have tribulation in the flesh; but I spare you.
Here we come to what is important. Paul knows that those who marry, whether we speak of men or women, will big problems in their marriages. Just look at how many today divorce relatively quickly. This is really not permitted.
He is therefore encouraging those who can to remain single and keep being single since this will bring less pains and tribulations upon the believer. This is why he tells us 'it is good not to touch a woman (sexually).'
In chapter 7, he does acknowledge the fact that many of us cannot remain single without falling into sin. He then tells the sisters and brothers to marry to avoid sinning. He also tells them how to give their mate the marriage dues and not to withhold this due.
One problem with marriage is obvious: many who marry want to divorce and marry someone else in 5 or 10 years. This is not Biblically permitted. This clearly is another reason for why singleness and abstinence may be good for some while others simply need to be married to avoid sinning.
If you need to have this expanded, you can ask for more.
