There seems to be more to our history than the text books teach us. Their seems to be evidence of very knowledgable and technological advances humans in the past. That seemed to be aware of math, geography, and distant civilization. I will argue that their is enough evidence for this to be a plausible hypothesis and con will argue against.
1st round - accept
2nd round - arguments
3rd round- rebuttals
4th round- closing arguments
Civilization- group of humans living in town structures, with language, law, and culture
Humans- the human species, not aliens or anything supernatural
Advanced- knowing math, geography, philosophy, science, biology and things we know today but did not know in recent past.
Thank you for your time and debating this subject
you claim that there is evidence that ancient civilisations existed and had knowledge entirely unknown to us, and that our history textbooks do not cover any of these gaps. However although you are partially correct in the fact that ancient civilisations such as the greco-roman period did have advanced knowledge that was later lost and had knowledge of other celestial bodies, we DO know why all this knowledge was lost and why there is such a large gap, and that it is covered by history textbooks. After the fall of the roman empire, a period known as the dark ages set it over much of Europe. during this period, most knowledge was largely destroyed by extremist puritans, and thus caused a large, technological rut in history, and only picked up once more during the renaissance period, where the Italians and french started taking a more positive outlook and started studying history and rediscovering all that lost knowledge. Archimedes, as one example, was one of the greatest minds of the greco-roman period, and did indeed make many fascinating geometrical discoveries which were later lost. However, we DO know what his discoveries were and why they disappeared, and they were eventually rediscovered at the start of the renaissance. Thus, there is no gap in the history the misses out on ancient discoveries.
