Answer:
Homology refers to the similarities between the group of species that share the common ancestor. The homology individuals arise from a common ancestor. They shows divergent evolution. The basic structure in homology is similar. The organs perform different function. They occur due to the evolutionary process.
Homoplasy refers to the shared characters of the group of species that do not share the common ancestor. The homoplasy do not involve the common ancestor. They shows convergent evolution. The basic structure in homoplasy is different. The organs perform the similar function. They occur due to the adaptation in different habitats.

People's daily experiences can contribute to their belief that earth/ species do not change because we are changing with it as it is happening. Also the changes happen gradually so you can't constantly see to believe it.
