22. Earth And Venus Are Alike
Nobody is certain as to how the belief that the Earth and the planet Venus are alike came about but that could have been because we didn’t have as much information about Venus as we had on the other planets. The assumption that the surface of Venus was much like planet Earth was formed on the basis of ignorance and not on actual fact.
It was only after a spacecraft was sent to Venus that astronomers understood that the planet had nothing in common with Earth and was quite an unwelcoming place.
