This website was made for a short homework assignment and since I like making webpages I made one just for it.
Space is a mysterious and undiscovered phenomenom that has always existed from the beginning of time yet life as we know it scientifically only currently exists on earth yet there is hope other life forms exist without a doubt. A piece of evidense on this is that we have already discovered yet havent been able to examine several planet with the same conditions as earth itself so it is possible life like here may exist in any of those discovered planets. Below: I give evidence that may prove their existence.
Almost everywhere scientists go on Earth, they find life: the cold, dark depths of the oceans; snuggled up to piping-hot hydrothermal vents; buried under the Antarctic ice and even in South America's parched Atacama Desert. Life can adapt to really tough conditions and, of course, most of the universe is going to be filled with habitats that are tough. For example, Mars is a harsh environment, but some of the microbes found on Earth, including the one shown here found deep in a mine, could survive beneath the surface of the Red Planet, he notes. These findings of so-called extremophiles have allowed scientists to scale back their list of requirements for extraterrestrial life. We just say it has to have some liquid water, and maybe that's it.
Space and beyond :)

Water is a key ingredient for life as we know it. And liquid water, it turns out, is fairly common in our local solar system. For example, evidence is mounting that liquid water may flow underneath the surface of Mars. Europa, a moon of Jupiter, appears to have a liquid ocean. So too might the Jovian moons Callisto and Ganymede. Saturn's moons Titan and Enceladus, may be watery. Even Venus might have a bit of liquid water in its atmosphere. There, you already have seven other worlds that might have liquid water, so far in our knowledge through examination of the planets by satellite view or by examination of its surface or surroundings by other methods
Scientists estimate that planet Earth is about 4.5 billion years old. The earliest evidence for life comes from 3.4 billion-year-old mats of bacteria called stromatolites in Australia. Since even bacteria are biologically complex, scientists think they arose from life forms that got a foothold on Earth even earlier. That suggests it wasn't terribly improbable, the evolution of life, because it happened very quickly. The caveat, of course, is that Earth could have won the evolutionary equivalent of the lottery, and no place else is quite so lucky.

There is no direct proof for any life beyond Earth, but the universe is home to a lot of stars. And as research over the past decade has shown, perhaps at least 50 percent of those stars harbor planets. Shostak estimates there are 1 trillion planets in the Milky Way alone. Surely some of them have undergone what Earth has undergone and developed life. The argument is simply one of probability.
This image from the Hubble Space Telescope shows a cluster of young stars in the Milky Way.
