why are france and england at odds with ech other in north america?

Answer 1

They were competing colonial empires. During this period, both France and England were both trying to gain strategic control of North American territories in order to benefit the mother countries. It's also important to remember that France and England had a centuries-long history of rivalry before that, so colonial competition between the two countries was more or less an extension of that rivalry. Both nations wanted to be more powerful than one another.
