Our earth has existed for billions of years and has certainly experienced a lot in its past. Countless cultures, religions and peoples have inhabited it and left their mark on it. Our home planet has tacitly handed down some of its past to us. More or less. Of course, coincidences have often led to the discovery of mysteries.
Mankind has been able to discover much of it so far and has been discussing and researching its meaning and purpose for centuries. Stonehenge in England, for example, or the ruined city of Machu Picchu in Peru. Humans have by no means discovered and explored everything that is mysterious, nor have they found answers to the many questions about the uniquenesses that have already been discovered. Mysterious artefacts, amazing finds and archaeological puzzles are still being uncovered.
