People have been studying it since they first saw it....
Scientists do not believe that any planet ever crashed into Venus.
Scientists think there may once have been large bodies of water on Venus, like oceans on Earth, but they all evaporated or something into space.
100 years or 115 years
The average age of the surface of Venus has been determined primarily from analyzing impact craters and counting the number of observable large craters. By studying the frequency and size distribution of these craters, scientists can estimate the age of the surface based on how quickly they accumulate over time. Additionally, data from spacecraft missions like Magellan have provided important insights into the geology and surface composition of Venus, contributing to our understanding of its age.

its unpredictable and imposibble to find out
Venus is volcanic, but it appears that activity has been minor for several hundred million years.
Venus has no natural satellites but probes have been sent their for many years now.
Venus can be the third brightes object in the sky, after the sun and moon. It would have been known about for thousands of years.
I'm not sure; I've never been to Venus... I'll let you know in about 65 years, okay?
19 years exactly
Yes, military scientists have have found these creatures and been studying them for a while, as well a other aliens i.e. Greys and Martians.
