nice topic, lol. our universe how big it is? our universe contains at least 50,000,000,000 galaxies, we do not mean 50 billion stars but at least 50 billion galaxies, each w/ billions of stars life our sun, and astronomers discovered that our universe are expanding. what is the origin of life? 1. scientists believe in evolution. 2.religion believe in creation. whats the answer? its up to you of what you believe but only one of this are true not both.
in my own opinion everthing, the painting, chair, houses, cars, computers, buildings etc. has his own designer and creator not they exist by chance like the cs the creator is valve always updating it.  [sorry for bad english]
