Prehistoric is a term used to describe the period of human history prior to the invention of writing systems. This period encompasses vast stretches of time from around 2.5 million years ago until approximately 5,000 years ago, during which humans lived in small nomadic bands and developed basic tools and technology such as stone tools, fire and animal domestication. The study of prehistoric materials poses several challenges due to its scope and antiquity; since there are no written records or archaeological evidence from this era, researchers must rely on other sources such as fossilized bones or artifacts.

One major challenge that researchers face is determining when certain events may have occurred due to the lack of written sources; for example, it can be difficult to pinpoint exactly when humans developed language or first began using fire. In addition, reconstructing environmental conditions at different points in prehistory can also be difficult without physical evidence for climate-related phenomena such as floods or droughts. Further complicating matters is the fact that many skeletal remains discovered from this era are incomplete or fragmentary enough that they are unable to provide much information about their original owners.

Another challenge involves interpreting cultural practices from prehistoric times; although some insights can be gained through studying archeological sites and artifacts left behind by ancient peoples, most cannot be directly linked with specific customs because there’s no written documentation available for comparison purposes. Additionally , much debate exists among scholars over how best interpret findings uncovered dig sites especially since interpretations often depend heavily upon one\’s background individual bias being brought table same time too – being able separate personal beliefs reality what truly happened precisely key here so valid conclusions reached while staying true fundamental principles research found along way remain consistent throughout course investigation itself otherwise subjective opinions seep into mix thus muddying waters unnecessarily .< br /> Therefore , studying material left behind by prehistoric cultures presents unique set problems which must overcome order reach reliable conclusions regarding past civilizations existed far before any form writing was invented let alone widely disseminated amongst masses begin with . Thankfully advances made within scientific community allow us gain greater understanding what transpired those days now all thanks collective effort many individuals contributed towards field overall too
