Hmmm, that statement is riddled with a lot of assumptions that are not scientific. For what is a fact, exactly? And who makes a fact a fact? There are a lot of matters about which scientists amongst themselves do not agree.
The science of archeology studies the relation between cultures and the material deposits they leave behind.
Or am I making things too heavy now?
No, not at all... It makes the anthropologist argument even stronger actually. Assumptions of course are not scientific...we can only speculate and an argument can be made if a person, or persons, have dealed, relived or experienced, what they consider to be, a fact!
What is a fact exactly? Well, that depends on the individual's, or group of people dealing with the fact, interpretation! Universal truths exist, but we give them the meaning we want to give them....
Unless you have an argument in mathematics, physics, or chemistry...and even there scientists are not always coherent.
But here is another question for you: Is archaeology a science? (Now I've gone too heavy...) Sorry, I miss those good old academic days...
They used to drive me mad!!!
Anyways, back to playmobil!!! Yes, If you want a proper medieval castle you'll have to plaster it!!!
I'll get my plaster first thing in the morning!!!
