麻煩幫我翻譯這個句子好嗎?

[棉花糖的故鄉]

因為實在不確定這句是啥意思
所以想請各位大大幫幫我
這句子有點長~~~~~><
Others think that the ships that have disappeard have been the victims of
bings from outer space who have snatched them from the surface of the
sea and taken them to some unknown world.
其中have been 這個完成式代表著何意義呢?

其他人認為這些船是從外太空來的生物的受害者，
這些生物把他們從海面上攫走，然後帶到某個未知世界去。

其他人則認為，那些消失於海上的船隻都已受害；
它們被來自外太空的生物自海上捉走，然後被置於陌名的另一個世界中
