This text explores the philosophical concept of being or existence specifically in relation to extraterrestrial life. The central inquiry focuses on whether extraterrestrials can be considered actually being entities within our universe. While we currently lack empirical evidence, records, or physical findings to confirm their presence, the possibility of their existence cannot be excluded a priori. The author draws a significant ontological distinction between extraterrestrials and extinct prehistoric creatures, such as dinosaurs. In the case of dinosaurs, their past existence is a verifiable fact supported by fossil records available to anyone. In contrast, the question of extraterrestrials pertains to their potential current existence—an actual being that remains unverified yet theoretically possible. The document delves into the nature of actuality and existence, examining how we categorize entities that occupy a space outside our direct observation. By comparing confirmed past existence with speculative present existence, the text highlights the complexities of determining the status of beings that exist beyond the current boundaries of human knowledge and scientific discovery.
