Do Aliens Exist? - Part 1
A question that has baffled many for years and years, do aliens exist? In this post I will be leaving some basic notes to hopefully persuade you into thinking aliens do exist. We will go through galaxy, study behavior and point out things that may stick out in our journey to reveal whether aliens exist or not. Follow the post along and leave your output below in the comment box if you wish too; I am happy to here replies.
So Many Stars - There Must Be Life?
Ever looked up at the night sky? Checked just how many starts there are in our galaxy? I am pretty sure you lost count; reason being is there are literally billions of stars up there. Although no scientist have yet to make any vivid proof of life beyond Earth; you think to yourself, with all those stars there must be something up there? Now 50% of stars are attached to a planet; with 1 trillion planets it would be pretty extraordinary if we were the only living creatures. There must be more, surely out of all those planets one has evolved into something similar to Earth? It would truly be amazing if Earth was the only planet after so many years the we can live on.
Water Isn’t A Problem
Heard on TV or the radio about neighboring planets in out solar system that have water? Well water is a key ingredient to live, without water there is of course no life. Evidence has emerged that Mars has water flowing under it’s surface. One of Jupiter’s moons Europa has been noted to have an ocean in it’s mists. Other moons such as Callisto, Ganymede, Titan and Enceladus also appear to have water in them or surrounding. Even Venus, an extremely hot planet has been said to contain at least a little water. So there you have it, that is 7 different places that have water amongst them; there might just be life, don’t you think? 
Life On Earth Evolved Fast
Scientists have said the Earth is over 4.5 billion years old. Yet the only sign of earth was at the 3.4 billion year old mark. Bacteria mats began to grow in Australia; now anyone that has studied science will know that it is a very complex thing. This leaves scientists with a conclusion that there must have been life before it had begun to grow. Something had to cause it to grow, it didn’t just start out of nowhere - thus there must have been something living on Earth beforehand that caused it.
