No, only if it cant be sensed in any one of the 5 ways. Not by all 5 ways.
Even atoms can be seen under an electron microscope, and moving atoms / molecules can be felt by the wind.
The senses that we have, were given to us by God. You are using these senses to measure whether God exists when infact he is not comparable to anything else in existance.
If I use what I have in terms of logic, understanding, reasoning, I can not come to any conclusion other then the fact there has to be a God.
Now, show me God.
You question is also answered in the Quran:
002.210
YUSUFALI: Will they wait until Allah comes to them in canopies of clouds, with angels (in His train) and the question is (thus) settled? but to Allah do all questions go back (for decision).
PICKTHAL: Wait they for naught else than that Allah should come unto them in the shadows of the clouds with the angels? Then the case would be already judged. All cases go back to Allah (for judgment).
SHAKIR: They do not wait aught but that Allah should come to them in the shadows of the clouds along with the angels, and the matter has (already) been decided; and (all) matters are returned to Allah.
002.211
YUSUFALI: Ask the Children of Israel how many clear (Signs) We have sent them. But if any one, after Allah's favour has come to him, substitutes (something else), Allah is strict in punishment.
PICKTHAL: Ask of the Children of Israel how many a clear revelation We gave them! He who altereth the grace of Allah after it hath come unto him (for him), lo! Allah is severe in punishment.
SHAKIR: Ask the Israelites how many a clear sign have We given them; and whoever changes the favor of Allah after it has come to him, then surely Allah is severe in requiting (evil).
002.212
YUSUFALI: The life of this world is alluring to those who reject faith, and they scoff at those who believe. But the righteous will be above them on the Day of Resurrection; for Allah bestows His abundance without measure on whom He will.
PICKTHAL: Beautified is the life of the world for those who disbelieve; they make a jest of the believers. But those who keep their duty to Allah will be above them on the Day of Resurrection. Allah giveth without stint to whom He will.
SHAKIR: The life of this world is made to seem fair to those who disbelieve, and they mock those who believe, and those who guard (against evil) shall be above them on the day of resurrection; and Allah gives means of subsistence to whom he pleases without measure.
Were you yourself created, or are you the creator? You question the existance of God yet are able to see His signs in your own existance and all around the world He created. If you are waiting as the verse above says, for God to come to you and show himself, that would be pointless as matter would be decided and there would be no test. The only time we will ever see our Creator is after we die.
