Valid question! The pictures of Earth taken from space have been captured by various satellites and spacecraft over the years, such as those from NASA, the European Space Agency (ESA), and other international space agencies. These images undergo rigorous scientific analysis and are cross-verified by multiple sources. Additionally, astronauts aboard the International Space Station (ISS) have also shared their firsthand experiences and images of Earth from space.
Moreover, there is a vast amount of scientific evidence supporting the fact that the Earth is a globe, including measurements of its curvature, satellite data, GPS technology, and global navigation systems. These pieces of evidence from different fields of science collectively reinforce the understanding of our planet's shape.
However, skepticism is always healthy, and it's good to critically evaluate information. If you have specific concerns or alternative viewpoints, I'm here to address them or provide further information.
