Our information about the medieval period is much more than the ancient period. Explain why?

Our information about the Modern period is also much more than that of the medieval period. In the most ancient period people were not much bothered about keeping record of events or of their activities. With the growth of civilisation, people became more conscious of recording events. With the development of language people now are more capable of recording events and conveying them to others. Availability of records is more in the case of middle ages than in the case of the ancient period as availability of records is more in the case of the modern period than in the case of the Middle ages. We have better methods of preserving records and better methods of disseminating them.
