The main reason is that Spiders and several other little animals such as scorpions split of from the main evolutionary branch going one way, and insects split off from the main branch going another way, and that happened a very long time ago.
The related reason is that the physical structures of spiders and insects are the same in that they do not have bones inside their legs and other body parts (so they have exoskeletons and are arthopods), but other than that almost everything about them is different.
