The hardcore atheists (not you) claim everything is scientifically proven, that we know it all
Can you provide documentation of "hardcore atheists claim everything is scientifically proven"? Or that "we know it all"?
More specifically, what do "hardcore atheists" have to do with paleontology or the fossil, Lucy?
I don't think anyone who has very firm beliefs can be objective here, weather they're creationist or atheist. Ideally they should be agnostic with no disposition at all.
Good. Science and scientists try very hard to keep belief from having any influence on their research. That's why they are so insistent about the definitions of the terminology they use. That's why they publish their results; so other scientists detect their errors and can detect any bias in the experiments, observations and discoveries, or conclusions.

I hope you don't confuse someone with "firm beliefs", with someone with knowledge of the discoveries and observations from a scientific field, someone who publishes their work for objective scientific review.
One thing I can tell you, the intense arguments that are occurring about various fossils and hypothesis are evidence of a vibrant branch of science. There are lots of expert eyes watching and checking everything that is published so everyone has to be careful that they report observations accurately.
As far as I know, all the errors in scientific theories that have been discovered were discovered by scientists. As far as I know, not a single error in evolutionary theory was corrected be creationists.

One important characteristic of a theory is that is has survived repeated attempts to falsify it. Contrary to your understanding, all available evidence confirms it. --Subbie
