We support the argument against the existence of Atlantis because the evidence found does not correlate with the story that Plato produced.
Evidence and Analysis
It appears that all of the "evidence" for Atlantis' validity is circumstantial in nature. Though there have been metal remnants believed to be identical to those used in the city, there is no way to prove that this statement is true. Some experts look to the mechanics of plate tectonics as proof that there was no possibility for the city to end up in its proposed location. The theory behind the entire conspiracy is due to nearly 8000 years of storytelling. Thus, error may lie in false propositions of the city's story. Essentially, Plato's rendition of the story of Atlantis might be completely different from what was told 8000 years before his existence.
Conclusion
By gathering evidence from numerous sources across the internet, we have come to the conclusion that the city of Atlantis is purely fictional. The story of Atlantis was passed down for many years before Plato learned about it. There have been no remains discovered from the city if it were to actually exist, leading us to believe Atlantis is not a historical place, but it is city from a long-existing fable.
