Humanity as a Non-Indigenous Species: An Evolutionary Mismatch and the Case for Extraterrestrial Origins

Key Points

This paper investigates the hypothesis that Homo sapiens are not native to Earth and examines the implications of this claim.
Utilized three decades of empirical observation and atmospheric analysis
Developed the Deshmukh GlobalShield Theory (DGST) as a framework for analysis
Discussed the implications of a chronic physiological mismatch with Earth's environment
Human physiology is significantly mismatched with solar radiation and native ecosystems.
Argues that human behavior arises from the need to recreate a lost protective habitat.
Suggests that humanity's historical drive to dominate nature reflects its origin as a displaced species.

Abstract

After three decades of empirical observation and atmospheric analysis, the Deshmukh GlobalShield Theory (DGST) proposes a revolutionary postulation: Homo sapiens is not anindigenous inhabitant of Planet Earth. While every other terrestrial organism exhibits aprofound biological synergy with Earth's natural environment, human physiology displays achronic mismatch with solar radiation and native ecosystems. This paper argues thathumanity arrived on Earth as a traveler from a different stellar origin, characterized by asuperior atmospheric shield. The persistent human drive to modify and dominate nature isinterpreted not as progress, but as a survival mechanism of a displaced species attempting torecreate its original, protected habitat.
