數十年來，科學家們一直對生命如何在地球上起源感到困惑。
For decades, scientists have puzzled over how life began on Earth.
一個引人注目的理論認為，古老的小行星扮演了生命必要成分的「快遞車」角色。
One compelling theory suggests that ancient asteroids acted as 'delivery trucks' for the essential ingredients of life.
早期地球是一個相對貧瘠的地方，缺乏生物演化所需的複雜化學反應。
Early Earth was a relatively barren place, missing the complex chemistry required for biological evolution.
對龍宮(Ryugu)等小行星樣本的研究揭示了大量的有機分子，包括RNA的必要成分尿嘧啶以及維生素B3。
Research on samples from asteroids like Ryugu has revealed a treasure trove of organic molecules, including uracil, an essential component of RNA, and Vitamin B3.
除了僅僅作為快遞員之外，這些小行星撞擊可能提供了「啟動」生命的必要能量。
Beyond merely acting as couriers, these asteroid impacts may have provided the necessary energy to 'jump-start' life.
激烈的碰撞產生了衝擊波和高熱，形成了撞擊誘發的熱液系統。
Violent collisions created shockwaves and intense heat, forming impact-induced hydrothermal systems.
儘管有些人猜測「胚種論」(Panspermia)——即完整的生物體從太空抵達地球的觀點，但主流科學共識傾向於「前生命播種」。
While some speculate about 'panspermia'—the idea that fully formed organisms arrived from space—the mainstream scientific consensus leans toward 'prebiotic seeding.'
這表明小行星只是提供了原始材料，而生命最終是在我們的星球上誕生的。
This suggests asteroids simply provided the raw materials, and life ultimately arose right here on our planet.
