如果要寫成文章的話 the pyramid were built by aliens.這句話改成委婉的說法，改成下面兩句話有什麼差別，用完成式會更委婉嗎?

The pyramids are built by aliens.我肯定是如此。(直述語氣) (100%) 用現在式來述說真實的事件（即永遠為真）。
The pyramids were built by aliens million years ago.動詞用過去式宜有時間點。
The pyramids are probably built by aliens.我對這件事的把握較高。(80%)
The pyramids are possibly built by aliens.我的把握不高。(50%)
The pyramids might be built by aliens.我的把握不高。(假設語氣)
The pyramids may be built by aliens.我的把握較高。
The pyramids might have been built by aliens....我的把握不高。用完成式動詞表示其時間點較另一事件早(即當時已經有了這個結果)。沒有委婉的作用。The pyramids might have been built by aliens ten thousand years before Jesus Christ was born.
