Matter has always existed. If you mean that invisible in the scriptures mean matter then I say that it was not organized. It always was.
Is matter visible or invisible?
Could you give me a reference which teaches God is only one eternal. Since God promises us eternal life if we remain obedient does that mean we did not have a beginning as well?
Before the mountains were brought forth, or ever thou hadst formed the earth and the world, even from everlasting to everlasting, thou art God.
Psalm 90:2
What is man, that thou art mindful of him? and the son of man, that thou visitest him?
Psalm 8:4
24 And God said, Let the earth bring forth the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind: and it was so. 25 And God made the beast of the earth after his kind, and cattle after their kind, and every thing that creepeth upon the earth after his kind: and God saw that it was good.
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 creepeth upon 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. 28 And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth. 29 And God said, Behold, I have given you every herb bearing seed, which is upon the face of all the earth, and every tree, in the which is the fruit of a tree yielding seed; to you it shall be for meat. 30 And to every beast of the earth, and to every fowl of the air, and to every thing that creepeth upon the earth, wherein there is life, I have given every green herb for meat: and it was so. 31 And God saw every thing that he had made, and, behold, it was very good. And the evening and the morning were the sixth day.
Genesis 1
Right there in Genesis 1, you see that man was not created until the sixth day, whereas only God was from everlasting to everlasting, the Alpha and Omega, the beginning and the end. All of these phrases refer only to God.
