Scientists argue we must look at the data with strict, cold facts. To them, saying 'we do not know what this is' does not mean 'it must be aliens.' NASA's official study team points out that we simply do not have enough high-quality, unclassified data to make any big claims. Until we have clear, repeatable measurements from multiple sensors, the idea of visitors from another world remains a guess of last resort. We must rule out everything else first.
