Infinite - Real!

If the infinite is really, where can we find it? Can we look up high enough to see it? Can we make a large enough measuring tape to measure it? Can we travel deep enough into space to finally get there? No like with counting to infinity, we could never stop and be there but have to continue counting, traveling, measuring, and looking forever.
So how can we find infinity and see if it is real? The infinite is found in math in pi, and e, and the square root of two, etcetera. The infinite is shown in math to be usable in shortened forms for mathematical processes. In Math, the infinite exists, and it is useable!
So why is it so hard to conceive of space being infinite? Have you ever seen a finite without an exterior? Look around at all the finite items you see. So why looking "out there" is the infinite so hard to see? However large a finite is whether it is a box,  one-story house, or a skyscraper, it still has an exterior. Therefore by infinite progression, outer space is infinite!
What about internally, is the space inside anything infinite too? Not the surface matter, but the space contained within it in its depth? Is there any limit to how much we can mentally magnify the space in anything? How deep is it? Infinitesimal, or infinite?
Inside and outside, is everything infinite and finite only an optical illusion? Are surfaces really hiding infinity beyond their view like the blue sky in daylight, which conceals the universe behind it? When we see the universe, should we consider the infinite hidden behind what we see? Don't look now, but the infinite is on the tip of your nose.
