The thing is first they dont have the capacity to do any major work.like sonar mapping sigirya etc.goverment doesnt allow to see if theres any hole in sigiriya entrance.They keep asking for the same permission.other point is his techonlogy is different than modern methods its hard for them to attain those mind states or manifest them.only looking for phsyical proofs is the only way that can prove to general public.But theres a lack may be because of distruction by enemy force.Few bit and pieces are there not enough to come to a conclusion.Good for them if they earn an income.But i'm interested.not being able to prove enough evidence is ok with me.even in india the only proof to show that buddha existed is a single pillar writing made by dharmashoka.others are all conclusions.his birth plave and all.
Even I would like if these people find something out of nothing, so that nobody gonna complain about Ravana. The problem is even after years and years they are still failed. Good luck with the investigation anyway.
Regarding your earlier comment about Dasa maha yodhayo, even I don't think there were giants like Aegir and Ran, but I do believe there were muscular people ( worriers ) led Dutugamunu's army. these people could do some stuff which other people cannot do and they tend to belive or I strongly believe because of their dictator or military mindset other people stay humble and serve as slaves. ( that's my personal opinion ).
about the buddha, I do believe one man cannot gather that much data, so buddha is a set of people. ( you have all the rights to go against me)
I'd rather talk about Ravana here than Buddha because people get offended when talking about religions.
