What are the practical obstacles to understanding this aspect of our past?

Practical obstacles to understanding aspects of our past include the scarcity of reliable historical records, which can lead to gaps in knowledge and differing interpretations. Additionally, biases in sources, whether from the perspective of historians or the cultural context of the time, can skew our understanding. Limited access to archaeological sites or artifacts, often due to political or environmental factors, further complicates efforts to reconstruct history accurately. Finally, the sheer complexity of human behavior and societal changes over time makes it challenging to draw definitive conclusions.
