The Bible says very little about your first two questions. The Bible is primarily a book about relationships between God and mankind. In it we learn how God loves us and how He wants us to love Him in return. Through its pages we see how others strove to do this and we are encouraged to do the same. The Bible, as the Word of God, gives us instructions on how to live (Matthew 4:4 Matthew 4:4But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceeds out of the mouth of God.
American King James Version×) and does not include every scientific or historical detail.
Perhaps the best passage we can turn to in connection with these questions is Genesis 1:27 Genesis 1:27So God created man in his own image, in the image of God created he him; male and female created he them.
American King James Version×. Here we read, “So God created man in His own image; in the image of God He created him; male and female He created them.” This passage indicates that mankind was created male and female, but says nothing about whether Adam had a navel.
In Genesis 2:7 Genesis 2:7And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
American King James Version×we note that when God created Adam, Adam became a nephesh—living being. The same Hebrew word is also used to describe animals in Genesis 1:20 Genesis 1:20And God said, Let the waters bring forth abundantly the moving creature that has life, and fowl that may fly above the earth in the open firmament of heaven.
American King James Version×. While both humans and animals are living creatures, made of flesh and therefore subject to death from the start, the Bible says that man was created to rule over “all things” including the animals (Psalms 8:4-8 Psalms 8:4-8 4 What is man, that you are mindful of him? and the son of man, that you visit him? 5 For you have made him a little lower than the angels, and have crowned him with glory and honor. 6 You made him to have dominion over the works of your hands; you have put all things under his feet: 7 All sheep and oxen, yes, and the beasts of the field; 8 The fowl of the air, and the fish of the sea, and whatever passes through the paths of the seas.
American King James Version×; Hebrews 2:6-8 Hebrews 2:6-8 6 But one in a certain place testified, saying, What is man, that you are mindful of him? or the son of man that you visit him? 7 You made him a little lower than the angels; you crowned him with glory and honor, and did set him over the works of your hands: 8 You have put all things in subjection under his feet. For in that he put all in subjection under him, he left nothing that is not put under him. But now we see not yet all things put under him.
American King James Version×). Furthermore, mankind has been offered the opportunity to become sons of God (John 1:12 John 1:12But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
American King James Version×; 1 John 3:1-3 1 John 3:1-3 1 Behold, what manner of love the Father has bestowed on us, that we should be called the sons of God: therefore the world knows us not, because it knew him not. 2 Beloved, now are we the sons of God, and it does not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is. 3 And every man that has this hope in him purifies himself, even as he is pure.
American King James Version×)—something not offered to animals.
In addition to the fact that mankind was designed in the image of God (Genesis 1:26-27 Genesis 1:26-27 26 And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creeps on the earth.
27 So God created man in his own image, in the image of God created he him; male and female created he them.
American King James Version×) with the potential to become sons of God, the Bible also reveals that at the time of death, the spirit of man goes up to God while the spirit of animals goes down to the earth (Ecclesiastes 3:21 Ecclesiastes 3:21Who knows the spirit of man that goes upward, and the spirit of the beast that goes downward to the earth?
American King James Version×). Animals are a wonderful part of God's creation and should be treated with respect, but they do not have the same potential as human beings.
