It is unlikely to propose these craft are ours because the basic science underlying the function of their propulsion system is simply undeveloped. You simply cannot hide developments like this from the greater scientific community. Quantum leaps do not happen in vacuum. Even in the Manhattan project, in the unclassified public work there is active research in nuclear physics. Nothing of the sort is happening here wrt gravitic propulsion/warping of space time. Floodgates open because in many of UAP encounters, witness testimony relay of telepathic communication initiated by the beings in the craft. It actually is how the scientific method works. If something that is very unlikely is now true, the likelihood of linked events predicated on this should be re-evaluated because the priors have changed.
