    If fish became amphibians through the process of evolution, then why do fish still exist?

    If you read up just a bit on basic evolutionary theory, you would have the answer right there and wouldn't  sound as clueless as you obviously are!

    Modern evolutionary theory doesn't really claim that one organism evolved from another in a linear fashion.  What is really claimed is that certain species share common ancestors. So, going off your example, modern fish and modern amphibians likely had an ancestor in common, and then their linages branched apart and came down to modern day.  Along the way, other branchings also occurred.  For example, amphibians and mammals share a more recent common ancestor than fishes and amphibians.

    For the same reason your parents are still alive after you were born. Evolution isn't a drastic change, it's small things. To use your example, a fish gave birth to something that was almost a fish, but not quite. The fish didn't become anything. Think of it closer to a birth defect rather than a transformation.

    Populations evolve, not class or order. A species, and even more so for any larger taxonomy group like fish, generally cannot evolve as a whole.

    Because Mother Nature decided that each type of fish was successful in its environment and so it became stablised to some extent, a drastic change in their repective environs will trigger more drastic changes and, as happens too often, extinction.  Amphibions are just  other creatures that have become successful in a particular niche, in tthe same way that some primates have become successful at an arborial socity and others have become successful at cfty society.
