The singers looked like ants.

 This is a simile, a figure of speech where two unlike things are compared using "like" or "as". In this case, the singers are being compared to ants.

Meaning:

The comparison suggests that the singers appeared very small and insignificant, perhaps due to being far away or being part of a large crowd. It could also imply that they were working diligently and tirelessly, like ants in a colony.

How to use it:

This phrase can be used to describe a situation where:

• Distance makes people look small: "From the top of the mountain, the hikers below looked like ants."
• A crowd is so large individuals seem insignificant: "The fans in the stadium looked like ants from the blimp overhead."
• People are working hard in a coordinated manner: "The construction workers swarmed over the site like ants, each carrying materials and working together."

Additional examples:

• "The protesters marched down the street like ants, their signs held high."
• "The dancers moved across the stage like ants, their movements precise and synchronized."
• "The children scattered across the playground like ants, each one busy with their own games."

Remember:

The effectiveness of this simile depends on the context and the image you want to create. Consider whether the comparison to ants accurately reflects the situation and the characteristics of the people you are describing.
