на русском:

Как вы, вероятно, знаете, Маргарет Уокер была афроамериканкой, и ее поэма относится к силе и выносливости ее предков женского пола, которые были рабами.

- Они коснулись земли, и зерно выросло."

В предыдущей строке говорится, что они сеяли семена на вспаханном поле. Очевидно, они сеяли семена вручную (не с машин), поэтому их руки приближались к земле и даже касались земли (земля здесь означает почву, а не планету Земля), и из этих семян зерно росло в полях.

-У них есть много чистых слов, чтобы сказать."

Их мысли и слова были чисты. Они не говорили плохо о людях и не использовали плохие слова.

на английском:

As you probably know, Margaret Walker was African-American, and her poem refers to the strength and endurance of her female ancestors who were slaves.

"They touched the ground, and the grain grew."

The previous line says that they sowed seeds in a plowed field. Obviously, they sowed seeds manually (not using machines), so their hands came close to the ground and even touched the ground (earth here means soil, not planet Earth), and from these seeds the grain grew in the fields.

"They have a lot of clean words to say."

Their thoughts and words were pure. They didn't say bad things about people or use bad words.

The universe is enormous, so the chances of us being the only living creatures are small. Although we think we are intelligent and that we know a lot about Space, we have only explored a very small area. We might be the only creatures that can travel in Space, but it is unlikely.

In fact, some people say that we might have been visited by aliens. These people point to ‘wonders’ such as Stonehenge in Britain and the Nazca lines in Peru as proof that aliens have been here.

So, what are the chances that there is life out there?
