Write a Python function `find_substring(strings, substring)` that checks if a given substring is present in any of the strings within a list. The function should return `True` if the substring is found in at least one string, and `False` otherwise.
#### Example Usage
```python [main.nopy]
find_substring(["red", "black", "white", "green", "orange"], "ack") # Returns: True
find_substring(["red", "black", "white", "green", "orange"], "abc") # Returns: False
find_substring(["red", "black", "white", "green", "orange"], "ange") # Returns: True
```
