It is true that it is hard to have a feel for the passage of time.
Homo sapiens has existed for 200,000 years, but recorded history only accounts for a few percent of that time. Similarly, the fossil record mostly only covers the last 600 million years, but Earth existed for 4 billion years before that, and life existed for much of that time. An awful lot must have happened during these earlier times, but they are almost a blank sheet.
