Confused Jew, Please discuss the ALL logistics of burning 700K to 900K humans outside. All the logistics to make this happen
 
This is really grim that you are making me do this but here is a rough answer:
Treblinka II was a death camp located northeast of Warsaw and operated from July 1942 to October 1943.
Beginning in the summer of 1942, bodies were buried in mass graves, dug with mechanical excavators. They were quickly filled and the stench became overwhelming.
Cremation began in early 1943.  Heinrich Himmler issued the order to erase evidence (Aktion 10005).  The mass graves were excavated, and corpses were burned on grill-like pyres.  Each pyre was about 25 meters long and 5 meters wide.  It was large enough to burn up to 3,000 bodies at once.
A layer of firewood was placed on the bottom. Heavier corpses were placed on top because body fat aided combustion. Fire was ignited underneath and the fat runoff helped ignite lower layers. As the fire consumed upper bodies, attendants added more corpses as fuel.
To reduce wood usage, corpses were dried, stacked tightly, and arranged for airflow. Body fat collected in trenches was sometimes reused as fuel. Nonetheless, burning 800,000 corpses likely required tens of thousands of tons of wood. Wood was collected from forests near the Bug River, sometimes transported via rail or carts.
All labor was done by Jewish Sonderkommando, under SS and Trawniki (Ukrainian) guards.  There were an estimated 300–400 men in rotating shifts and they dug up corpses from the mass graves, transported them to the pyres, stacked the bodies, and burned them.  After the bodies were burned, the crushed the bones with a mortar and pestle and scattered the ashes in surrounding pits or the forests.
At the peak rate, 8,000 to 15,000 bodies were burned.  A 1945 Polish investigation found that ~16–20 pyres were used in sequence.  The whole operation lasted 5–6 months (from early 1943 to August 1943).  The German firm Fuchs built a custom excavator to dig graves and exhume corposes.
There were testimonies from SS guards and Sonderkommandos who survived or escaped.
After the burning, ashes were sifted for gold teeth and valuables. Bones were removed, crushed, and scattered. Soil in parts of Treblinka today contains several meters of ash and bone residue.
After the war, Polish forensic teams found mass graves filled with burnt human remains and burned soil layers. Ground-penetrating radar (GPR) in the 2000s confirmed more mass grave sites and disturbed earth consistent with cremation pits.
There might be some things in there that are slightly off, but I have no idea how you will try to refute that.
