We often say there is just too much out there. You can't even possibly see everything that this universe has to offer in a million year or even a billion year.
Consider an image with resolution of 640X420 (i.e. better than standard TVs and pretty close to DVD) and RGB color depth of 0-255. Although not the best, this is perhaps a good approximation for the human eye. With this setup there are actually only 4457 billion images possible. Let's say you were watching one image per second then in about 141,332 years you would have seen everything that is possible to see! If you were making video at 25 fps with each frame being unique then within 5653 years you would no longer have anything else to shoot.
