نَّ فِى خَلۡقِ ٱلسَّمَـٰوَٲتِ وَٱلۡأَرۡضِ وَٱخۡتِلَـٰفِ ٱلَّيۡلِ وَٱلنَّهَارِ وَٱلۡفُلۡكِ ٱلَّتِى تَجۡرِى فِى ٱلۡبَحۡرِ بِمَا يَنفَعُ ٱلنَّاسَ وَمَآ أَنزَلَ ٱللَّهُ مِنَ ٱلسَّمَآءِ مِن مَّآءٍ۬ فَأَحۡيَا بِهِ ٱلۡأَرۡضَ بَعۡدَ مَوۡتِہَا وَبَثَّ فِيہَا مِن ڪُلِّ دَآبَّةٍ۬ وَتَصۡرِيفِ ٱلرِّيَـٰحِ وَٱلسَّحَابِ ٱلۡمُسَخَّرِ بَيۡنَ ٱلسَّمَآءِ وَٱلۡأَرۡضِ لَأَيَـٰتٍ۬ لِّقَوۡمٍ۬ يَعۡقِلُونَ . (سورة البقرة:۱۶۴)

"SURELY, IN THE CREATION OF HEAVENS AND EARTH, AND THE ALTERNATION OF NIGHT AND DAY, AND THE SHIPS THAT SAIL IN THE SEA WITH WHAT BENEFITS MEN, AND THE WATER ALLAH SENT DOWN FROM THE SKY, THEN REVIVED WITH IT THE EARTH AFTER ITS BEING DEAD, AND SPREAD OVER IT OF EACH CREATURE, AND IN THE TURNING OF WINDS, AND IN THE CLOUDS EMPLOYED TO SERVE BETWEEN HEAVEN AND EARTH: THERE ARE SIGNS FOR THOSE WHO HAVE SENSE." (SURAH AL-BAQARAH:164)

Allah Ta'alah has repeatedly pointed out in the Quran those facts about the universe which are clearly open to our eyes and if one ponders about them with an open mind then they are a clear evidence about the existence of Allah Ta'alah and His Oneness (Tauheed). The way all the creatures in the universe keep working, the way the Sun and the Moon go about their movement in a disciplined manner, the way the seas and the oceans not only store great amounts of water but also connect different parts of land through vessels that float on them and transport what humans need through these vessels, and the way winds and the clouds provide sustenance for human beings; only someone who is completely oblivious of all these facts can believe that this whole system is running by itself in such a complex manner by itself with someone running it.
