For your information, scientific evidence denies the existence of gas chambers.

For your information, eyewitnesses confirm the holocaust, gas chambers and all. For instance,https://en.wikipedia.org/wiki/Holocaust_denial#Former_SS_members
Critics of Holocaust denial also include members of the Auschwitz SS. Camp physician and SS-Untersturmführer Hans Münch considered the facts of Auschwitz "so firmly determined that one cannot have any doubt at all", and described those who negate what happened at the camp as "malevolent" people who have "personal interest to want to bury in silence things that cannot be buried in silence".[170] Zyklon B handler and SS-Oberscharführer Josef Klehr has said that anyone who maintains that nobody was gassed at Auschwitz must be "crazy or in the wrong".[171] SS-Unterscharführer Oswald Kaduk has stated that he does not consider those who maintain such a thing as normal people.[172] Hearing about Holocaust denial compelled former SS-Rottenführer Oskar Gröning to publicly speak about what he witnessed at Auschwitz, and denounce Holocaust deniers,[173] stating: I would like you to believe me. I saw the gas chambers. I saw the crematoria. I saw the open fires. I was on the ramp when the selections took place. I would like you to believe that these atrocities happened because I was there.[174][175]
Forget about "witness", because actually the men mentioned in that link are not alive, so, it is possible that those words don't belong to them.
Lets go to the scientific side.
Show me the gas chambers. This is to say, according to your theory, how those were built.
You must make your scientific theory credible by supporting it with evidence, no assumptions will be accepted but evidence. The theory's explanation must have solid back up with the technology and methods which apply for the building of a gas chamber.
Any failure to the scientific method requirements will automatically discard your scientific theory probing that there were gas chambers in those concentration camps.
Your theory must include samples which back up the validity of it.
Again, forget about "witness", same as DNA has been obtained from fossils of species which lived in ancient times, same as well scientific evidence can be obtained from gas chambers that existed 70 years ago. The original buildings still stand erected over there, no way to evade having a study of their structure to become gas chambers as you are claiming.
