You would need to research farther because both Frogs and toads come from tadpoles.

Tadpoles will eventually develop into an adult amphibian - frog or toad, for example.
Tadpoles are the young of frogs and toads.
Tadpoles of frogs tend to have slender bodies with long tails, while tadpoles of toads usually have shorter bodies and stubbier tails. Additionally, frog tadpoles typically have smooth skin, whereas toad tadpoles may have more bumpy or rough textures to their skin.
Tadpoles eat alga until they develop into a frog, toad or newt.
Tadpoles grow into frogs or toads, depending on the species of the tadpole.
frog tadpoles are usually brown and cane toads are black with there mouth and nose see through but some frogs such as the green mountain frog has jet black tadpoles.
The tadpole is the juvenile stage. As it gets older, it turns into a frog, not a fish.
I assume you are asking about the frog and/or toad life cycle. First is the egg. Eggs hatch into tadpoles. So to answer your question, eggs come before tadpoles.
Young toads are called tadpoles. Tadpoles are the larval stage of a toad's life cycle, starting as fertilized eggs laid in water. They undergo metamorphosis, developing legs and lungs as they transition into adult toads. Tadpoles primarily feed on algae and plant matter before becoming carnivorous as adults.
Grab yourself a dissecting scope; put the tadpole, bellyup, in a dish under the scope. Get a good look inside the tadpoles mouth, and compare it to a species key for frog tadpoles. The number/formation of the teeth will tell you what species of frog your tadpole will turn into.
