Was Crocodile stronger at Marineford? Or was he holding back in Alabasta?

 During the Alabasta arc, Crocodile displayed a level of power that was initially considered overwhelming by the Straw Hat Pirates. He possessed the Logia-type Devil Fruit called the Suna Suna no Mi (Sand-Sand Fruit), which granted him the ability to control and transform into sand. He had a reputation as a Shichibukai and controlled the desert kingdom of Alabasta from the shadows. His strength was showcased through his battles with Luffy and others. At Marineford, Crocodile was present as part of the war that took place at Marine Headquarters. While he did participate in the battle, he didn't display the same level of dominance as some other powerful characters present. This has led fans to speculate that he might not have been as strong as initially portrayed in Alabasta. It's important to note that power scaling and character abilities can be subject to interpretation and development by the author. Oda often keeps details deliberately open-ended to keep the story intriguing.

people do not come from the Earth According to science

Meteorites, according to science, brought life to Earth. These meteorites carried microorganisms that eventually evolved. However, not everyone agrees.

People did not evolve alongside other life forms on Earth, according to Ellis Silver, an American ecologist, but arrived tens or hundreds of thousands of years ago.

In support of this hypothesis, Silver claims that some of the chronic diseases that plague humans may be evidence that we evolved in a world with less gravity.

According to initial reports, the surge occurred after news of a celebrity at a bar in the nightlife district spread.

Another fact supporting the scientist's thesis is the presence of some unusual human characteristics, such as babies' heads being so large that it is difficult for women to give birth. "This is a problem that no other species on the planet has," the scientist claims.

"I believe many of our health problems stem from the simple fact that our internal biological clocks have evolved to perceive a 25-hour workday, despite the fact that a day on Earth lasts only 24 hours," Silver writes.
