Contact Getting the "Twin Paradox" Wrong

Godzilla is an incredibly gigantic lizard-like dinosaur who demolishes everything in it's path. However, the science of Godzilla is luckily, for the humans on this planet, highly unrealistic and will probably never happen in our lifetime. First off Godzilla in order for Godzilla to be able to keep healthy, and walk around like no problem he would need to consume about 215 million calories a day. The average man is about 125,822 calories. With that said Godzilla would need to consume about 1,708 people a day just to stay healthy. Godzilla is 164,000 tons; the heaviest animal to ever live on earth was a dinosaur that was 100 tons, 70ft tall, 115 ft long, and had four legs to equally separate the weight. Godzilla only stand on two legs. Therefore his weight alone would cause for his bones to be equally as strong, otherwise his organs and inside would fail and Godzilla would turn into  mesh. Along with his insides literally failing, Godzilla's volume would increase tremendously. In that being said his destiny would also increase tremendously. If he was to just increase his size 50x his density would be 8x10-6 which is 1/10 less than the density of hydrogen. Meaning that since Godzilla is even bigger than 50x, Godzilla would for sure be easily blown away by any little force acted on him. Some monster he is when put into a realistic perspective.
