Archaeology

Rabbi Shalom Rabbi. I am 16 years old, studying in a high school yeshiva and a good observant of mitzvot. I will try to explain my difficulty. Recently I was wandering around the Internet and saw some articles and videos that say that the Exodus from Egypt did not happen and was not created. There are of course other difficulties in the conquest of the land, etc. I think that this bothers me less.
There is no evidence that Israel was in Egypt/left it/defeated it/or did anything there. And the Egyptians are known as the people who document the most! I asked the yeshiva rabbi about it and he answered me with demagogy.
I would be happy if you could clarify for me why archaeological findings are not necessary or do not have such a strong connection. Thank you,
Liran
