You don’t have to. Fotolia is now Adobe Stock so you should be able to pay to license this logo.

Ok, then explain this, how to create those

[Monika Gause · Accepted solution]

The principle is to find the building blocks. Then create some shpes like this:

Read the documentation on how to work with shapes, create them, move them, rotate them, duplicate them.

Then use construction methods, such as the shapebuilder tool or live paint tool (again: read the documentation)

Then apply gradients and solid color (and again: read the documentation)
