Throughout history of science, all scientific literature was written in Latin. Only recently has it been written in English and modern langurages.
We use latin names so scientists that speak different languages can understand what they are talking about.
Another reason is that many plants and animals have common names that differ by region.
Having a Latin name avoids confusion among scientists.
So did you know our planets are not called after Latin names but named after Greek and roman gods – like Venus is named after the goddess of beauty because of how bright it is , and mars is named after the god of war – because it is red and big.
We won’t change these names because they are used so often in today’s science.
