Something had to create everything. If you are thinking about the Big Bang, then think about this... what created the Big Bang? If it was a star... what created the star? it had to have been God. The way i see it there is no way it could have been anything else.

when looking at the overall appearance of the most advanced robot ( ASIMO) it really makes me faint..it looks more like a doll..why are scientists making a humanoid that looks so plastic..
a friend of mine ( electrical engineer) made a graduation project of a replica of the " Terminator Arm" from the terminator movie & it only weigthed 2.5 kg..& it was fully designed & programed in less than 5 months..it could hold a cup,shake a hand, or break a neck...
i don't know why scientists pick those crapy designs for something called humanoid..is there an explanation for this ?

When blood is deprived of oxygen its not red, which is why your veins have a bluish color but if you fall down and scrape yourself the blood will always be red because of the oxygen in the Earth's atmosphere. Hypothetically if I created an environment without any oxygen in the air, and I cut a vein, would the blood be blue?
