In this topic, we learn how to talk about theories and evidence. Sometimes people have interesting ideas or theories, but there is not enough proof to say they are true. We use this phrase to show that more information is needed. This topic helps students use vocabulary and grammar to describe situations where something cannot be confirmed.
Examples:
There isn’t enough evidence to prove the theory.
The scientists need more data.
We must wait until we have facts.
It could be true, but we don’t know yet.
