Yes. Allah has sent down miracles, revelations and messengers to give
clear proofs He exists and more important, what we should do once we
come to this realization.
Allah has sent prophets and messengers with many proofs throughout the
ages for people to be able to clearly see with their own eyes and to be
able to use their own senses the miracles and proofs pointing to the
fact, Allah does in fact, exist.
Miracles of prophets and messengers of Allah have come to people
through the ages. Moses (peace be upon him) showed many miracles to
pharaoh and to the children of Israel. Plagues, locusts, water turning
to blood, his stick becoming a snake, the voice in the burning bush and
the parting of the Red Sea are clear miracles for the people of Moses
time.
Again, Allah sent Jesus, the son of Mary (peace be upon him) with clear
miracles for the people of his time. Speaking from the cradle while
still a new born infant, creating birds from clay, curing the sick,
giving sight to the blind and even bringing a dead man back to life,
were all clear signs to the people to know Jesus (peace be upon him) was
a messenger of Allah as was Moses before him.
Muhammad (peace be upon him) was the last and final messenger of Allah,
and he was sent to all of mankind. Allah sent him with a number of
miracles, not the least of which was the Quran. The predictions and
prophecies of Muhammad (peace be upon him) have come true even in this
century and the Quran has been used to convince even scientists of the
existence of Allah.

The Quran is the best of proofs for the existence of Allah and today
over one and half billion people memorize and recite from the exact
text, in the exact same language it was revealed in; Arabic. More than
10 million Muslims have completely memorized the entire Quran from cover
to cover, and can recite it from memory without looking at it.
No one sees or hears Allah, not even the prophet Muhammad (peace be
upon him). Nor are we able to use our senses to make some kind of
contact with Him. However, we are encouraged in Islam to use our senses
and our common sense to recognize this entire universe could not
possibly come into existence on its own. Something had to design it all
and then put it into motion. This is beyond our ability to do, yet it is
something we can understand.
We know from the teachings of Muhammad (peace be upon him) the proofs
for the existence of God (Allah) are most obvious to us in our everyday
surroundings. Anyone with understanding would quickly acknowledge His
existence provided they are not so stubborn as to ignore the obvious
evidences right in front of us.
We don't have to see an artist to recognize a painting, correct? So, if
we see paintings without seeing artists painting them, in the same way,
we can believe Allah created everything without having to see Him (or
touch, or hear, etc.).
