As pointed out the whole easter bunny thing is a very anglo-saxon thing. The egg is more universal though, but so what? Eggs are a really tiny part of traditional (Especially early) easter celebrations. At best you can say it is evidence for pagan influence on easter, it is not evidence for easter being a pagan holiday.

Again, traditionally easter has consisted of going to Church and celebrating there. Things such a the easter bunny and egg hunts are innovations that came long after paganism had become nonexistant in what was the roman empire. You also have to remember how massive easter was in the past. In western christianity christmas became the ”main” holiday. But traditionally easter has always been the big one with many special celebrations, unique hymns, Church celebrations etc. Especially after the religion was legalized.
