What is time? Here is my definition:

Time is the process by which reality moves from past, present, to future

I believe that consciousness couldn't exist without time. To demonstrate this, first imagine a consciousness that lasts for 2 minutes. This would be a brief amount of time, but enough to experience a few thoughts and senses. Now imagine a consciousness that lasts for a quarter of a second. This would be like a flash. And finally, try to imagine a consciousness that lasts for 0 seconds. In this case, the flash wouldn't even occur and consciousness would not exist. In this regard, time can be thought of as the window that allows consciousness to exist.
