The Earth has been around for approximately 4.6 billions of years. Humans first evolved from I believe apes around 5 million years ago, with Homo Sapiens evolving around 2 million years ago or so. The current calendar system we use today, the Gregorian system (in most western nations like America) marks the year 0 as the year Jesus Christ was born, not when the Earth was formed. Years before Jesus' birth are marked as B.C., with the numbers getting higher the earlier you go. In the Japanese system, the year is marked by how long the current Emperor has been in power, making the current year (2017) Heisei 29 in traditional Japanese calendars.

hola:

ef0: daños leves. algunas tejas caídas y otras pequeñas piezas de los tejados arrancadas, algunos daños en canaletas, ramas de árboles rotas y algunos árboles poco profundos arrancados. los tornados que no causan daños visibles (por ejemplo aquellos que se producen en campos abiertos) se valoran siempre como de ef0.

ef1: daños moderados. tejados seriamente despedazados, caravanas y casetas volcadas o seriamente dañadas, perdida de puertas exteriores y ventanas y otros cristales rotos.

ef5: daños increíbles. las casas fuertes pueden quedar arrasadas hasta los cimientos, las estructuras de hormigón armado dañadas críticamente, los edificios altos sufren graves deformaciones estructurales. devastaciones increíbles.

y según esto creo que puedes sacar tus conclusiones. y la verdad la escala ef10 si no se decirte por que no la eh visto o mejor dicho estudiado. espero que te sirva. suerte.

It is useful for historians to write narratives so that history can be passed on from their point of view. think about a story being told in third person, then think about it again being told in first person, by someone who actually experienced the event.
