I think before ''EARTH'' was made, it was just a star. I think that star turned 10,000 degrees!! Fahrenheit and celsius. Or I would say centigrade. I have no idea of how people were made. I have no idea about animals either. I do know why the ground sucks things in. E.G. A spider dies then you show your friend the next day. It does not look ugly. That means it is organic. If a fake spider is on the ground for more than a day, it will ook ugly. So that means it is inorganic.
