Firebase Analytics does not expose the historical event level data. It only exposes aggregate information.

Complete event data is only available from the moment you enabled the BigQuery connection. No data from before that time will be added to BigQuery.

The data from the analytics reports that is shown in the Firebase Console is not available through an API. See Is there any api for dashboard analytics data?
