The existence of God can be proved at both levels — at the “macro-level” as well as at the “micro-level”.
Here are some proofs at the macro-level.
TWO PROOFS AT THE MACRO-LEVEL
- Look at the following photo.

It is a photo of a man-made “Artificial Womb”.
It can be used to grow only a fetus which may have already grown to the extent of about 20 weeks in a female womb — to full term, while the female womb created by God can grow a fetus from the day a zygote is formed by the fusion of a cell of egg and a cell of the sperm, as shown in the following diagram.

2. As mentioned by Bob Stein in his article “Japanese scientists race to create human eggs and sperm in the lab” published in the September 2023 issue of Health News, Florida [1], the developmental geneticist Katsuhiko Hayashi has been able to grow the cells of human sperm as well as the cells of human eggs from the stem cells of human skin.
Do you notice that he grew such cells from the cells of human skin?
Think of the days, when no man should have existed on the Earth, how the first man should have come into existence.
How any entity, who-so-ever should have been able to create the “first ancestor (not the most recent common ancestor, known as MRCA) of the man” and the “first ancestor of the woman” on the Earth, should have been able to create the cells of the male sperm and the cells of the female eggs?
Since at that time no man or woman lived on the Earth, this entity could have not been able to procure any cells of human skin, to create the cells of the sperm and the eggs.
But if it would have not been possible for this entity to create the cells of human sperm and human eggs — none of us would have been living on the Earth.
Don’t we regard such an entity only as “God”?
A PROOF AT THE MICRO-LEVEL
Here is a proof at the micro-level.
The following activities take place after the fusion of the cell of the human sperm and the cell of a human egg.
When a zygote is formed by the fusion of a female egg, it does not undergo any change for the first 12 hours after conception but after 30 hours, it divides into two cells and about 15 hours later — the two cells divide into four cells.
After three days, the fertilized egg becomes as big as a berry-like structure, which consists of about 16 cells. This berry consists of two layers and its inner layer serves as the embryo.
In the next two or three days the number of its cells grows to approximately 200 and upward.
After 13 to 20 weeks of gestation, the total number of the cells increases by the factor 4.3 from 3 trillion to 13 trillion.
After mid-gestation to full term, the total number of cells increases by a factor of 2.9 to 38 trillion.
In a way, the zygote acts as the parent of the cells into which it gets divided.
If we may call the cells into which it gets divided “its babies”, these babies become the parents of the cells produced by them, and this process runs through till the final stage of gestation.
Just imagine, what may be happening during the 12 hours after the conception.
We may expect that during this time an instruction telling the zygote to get split into two cells may be getting downloaded into its memory, as well as the information regarding what its baby cells are supposed to do in how much time.
Now imagine what may be happening after 30 hours when it divides into two cells.
It must be transferring the information received by it about what the baby cells are supposed to do into the memory of the cells produced by it.
Though, initially for some time, same process may be carrying on in this manner but at some stage, such cells may be getting ready to get assembled into various limbs of the body.
By the time, the cells may start getting assembled, the parent cells may also transfer the information regarding where their baby cells have to be lodged for assembly in the form of “Θ”, “Φ” and their radial distance “R” from the parent cell, as shown in the following diagram.

Since the fully grown-up fetus consists of more than 200 types of cells, the parent cells must be also transferring the information regarding the types of the cells to be produced and the biological process of creating the type of the cells to be produced, as well.
As we may guess, since it has to be ensured that the cells which are supposed to become a part of, say, the nose may not become a part of the heart or liver or kidney and vice versa, don’t you think it should be necessary for all parent cells to assign a unique identity to each baby cell produced by them in the form of a unique serial number?
Obviously, every step may have to be pre-programmed for all the 38 trillion cells.
Who do you think — must have developed such program according to which all cells may be getting assembled into various parts of the body?
Don’t you think unless which-so-ever entity should have developed such program, should have known everything that is written in Gray’s book on human anatomy — it should have not been possible for it to develop such program?

Besides knowing what is written in this book, don’t you think — such entity should have been knowing the biological system of loading such information into the memory of various baby cells which become the parent cells of the cells produced by them, also?
So is it wrong to assume that this entity had all the characteristics — the God is supposed to have according to us?
Since human evolution is still an ongoing process, don’t you think — such entity may have not become extinct?
IF IT HAS NOT BECOME EXTINCT — DOES IT NOT SERVE AS UNDISPUTABLE PROOF OF THE EXISTENCE OF GOD?
