The Greatness of Allah Subhanahu wa Ta'aala is impossible to describe. One can make all the trees of the world into pens and all the waters in the world into ink, yet the praises of Allah are infinite; we will tire before even reaching 1% of His praises.
Look around at the creation of Allah, look at the sun, moon, stars. Look at the plants, trees, flowers, water. Look at yourself. Look at your fingers, your nails, your fingertips. Look at the beauty all around you. Contemplate and realize that if the creation can be so beautiful, then how Awesome must the Creator be?
Give thanks to Allah, praise Allah, and keep seeing His signs across the globe. One does not have to see Allah written in the skies with clouds. One simply has to see the clouds themselves to realize the Superb Magnificence of Allah, and how only He can be the Creator of all creations.
