Is absinthe and Everclear the same thing?

Could you clarify for me if absinthe and Everclear are indeed one and the same? I've heard conflicting opinions and I'm curious to know the true difference between these two alcoholic beverages, if any exist at all. Do they share similar properties or are they distinctly different in terms of their production methods, ingredients, and overall taste profile? I'm eager to learn more about this topic and would appreciate your expert insights.
