If you're going to use a deity as the basis of a scientific argument, you'll have to demonstrate in terms acceptable to scientific inquiry that he exists and has the characteristics you ascribe to him.
I can tell others that God is One with no equal, peer or associate, and has no wife, son or daughters. This is the essence of all the heavenly religion. (And I swear to this). Anyone, that does not hold fast with this First of all the Commandments of God; anyone like this will be a loser, and will regret when he will die and go to his next world.
And to believe in all the apostles and prophets including Moses, Jesus and Mohammed, and to believe in all the heavenly books: including the Torah (included in the Old Testament), the Gospel and the Quran revealed to Prophet Mohammed. (And I swear to this.) Or else man will lose – in case he discriminates between the apostles of God: so that he will believe in some and disbelieve in some others.
But in case one wrangles concerning God's existence, this will be the most grievous loss; because God's existence is more real than man's existence. (And I swear to this.)
Such a man: the atheist, will not respond to any logic or proof. Mostly he will not respond; because he does not want to believe, and will follow some ways like: has the hen come from the egg, or is it the egg that has come from the hen, and will go circling in this vicious circle. But of course there should have been an initial hen that would have started all this chain.
Many philosophies that deny God the Creator, are mysterious and complex; and they say: that none has understood the philosophy of such and such philosophers, but even though many will follow such philosophies without understanding them.
It is a matter of guidance; God guides the one that deserves to be guided: whether he be educated and graduated or he be ignorant and illiterate. Anyone worthy of guidance (being modest, not proud; kind-hearted to orphans, widows and poor people) then God will guide him. But anyone proud over people, and does not help the weak for the sake of God, then God will make him hard-hearted, and will leave him to devils to confound him.
About some atheists who deny God and say: there is no god, and things are going on spontaneously, and we live our life then die and there is nothing after death; here God – be glorified – said in the Quran 45: 24
وَقَالُوا مَا هِيَ إِلَّا حَيَاتُنَا الدُّنْيَا نَمُوتُ وَنَحْيَا وَمَا يُهْلِكُنَا إِلَّا الدَّهْرُ وَمَا لَهُم بِذَلِكَ مِنْ عِلْمٍ إِنْ هُمْ إِلَّا يَظُنُّونَ
The explanation: (They say: "There is nothing but our [present] Worldly life; we die and our [children] live, and nothing but Time [factors] destroy us." Of that they have no knowledge, they merely conjecture.)
When man truly wants to believe, then let him ask God to guide him, and He will guide him if He please; like Prophet Abraham when he searched about his Lord, and he said as in the Quran 6: 77
فَلَمَّا رَأَى الْقَمَرَ بَازِغًا قَالَ هَذَا رَبِّي فَلَمَّا أَفَلَ قَالَ لَئِن لَّمْ يَهْدِنِي رَبِّي لأكُونَنَّ مِنَ الْقَوْمِ الضَّالِّينَ
The explanation: (When he saw the moon rising, he said: "This is my Lord." But when it set, he said: "If my Lord does not guide me, I shall surely be of the people gone astray.")
And God – be glorified – sent to him the angel telling him who is his Glorious Lord –be celebrated His praise.
